On April 26, arguably the biggest movie of 2019 will be released. I'm talking about Avengers: Endgame, a film that recently topped Fandango's list of most anticipated movies of 2019 (besting Captain Marvel and Star Wars: Episode IX). The movie is so big that we may as well declare April Avengers: Endgame month.

When Avengers: Endgame hits theaters, it'll mark the end of an era. It was over ten years ago when Iron Man kicked off the Marvel Cinematic Universe, paving the road to where we are now. It also began the Thanos storyline as the Mad Titan set out to collect the Infinity Stones.

Here's everything you need to know about Avengers: Endgame.

The latest Avengers: Endgame news

March 25 - Avengers: Endgame is likely over 3 hours long

Avengers: Endgame directors Joe and Anthony Russo recently teased the film would be long—really long. Now, thanks to an AMC listing, we might actually know the movie's final runtime: 3 hours and two minutes.

Considering the stakes involved in the upcoming film, hearing that Avengers: Endgame is long is no real surprise. The Avengers have to undo the damage done by Thanos, and it's not going to be a cake walk.

If the movie is entertaining, audiences won't even realize the length when they're sitting in the theaters. Avengers: Infinity War was 2 hours and 29 minutes long, but it hardly felt like it. My guess is three hours will fly by.

In addition to listing the runtime for Avengers: Endgame, AMC also lists a short synopsis:

The grave course of events set in motion by Thanos that wiped out half the universe and fractured the Avengers ranks compels the remaining Avengers to take one final stand in Marvel Studios' grand conclusion to twenty-two films, Avengers: Endgame.

March 21 - Avengers: Endgame TV spot teases crucial moment in fight against Thanos

Marvel has introduced the first TV spot for Avengers: Endgame, and while it doesn't include any footage we haven't seen, it teases a big moment in the fight against Thanos.

"Today we have a chance to take it all back," a voiceover from Steve Rogers says.

"Take it all back," of course, refers to the devastating snap from Avengers: Infinity War. But how, exactly, will the Avengers take it all back?

With time travel a rumored plot point in Avengers: Endgame, this new TV spot could hint at a plan to hop into the Quantum Realm, where a time vortex could be utilized to undo the snap by Thanos.

The Avengers will take it all back when Avengers: Endgame hits theaters on April 26.

Here's when you can buy Avengers: Endgame tickets

March 19 – Don't believe what you see in those Avengers Trailers

We're ready for Avengers: Endgame. We're anxiously keeping an eye out for Avengers tickets, we're ready for Captain Marvel to save the day and we can't wait to see who lives and who dies in the end.

The Avengers: Endgame trailers have us anxious for the film's release on April 26, but as it turns out, they might be a misleading. Director Joe Russo has confirmed a long-running theory that the trailers contain extra scenes that won't make it to the final cut, in a bid to keep fans in suspense.

Speaking to Empire Online, Joe Russo confirmed:

We talked about all scales of marketing. The thing that's most important to us is that we preserve the surprise of the narrative. When I was a kid and saw The Empire Strikes Back at 11am on the day it opened…it so profoundly moved me because I didn't know a damn thing about the story I was going to watch. We're trying to replicate that experience.

All of this means we're going to have to wait until April 26 to know exactly what happens. Which shots do you think are misleading us? Check out the trailer below and let us know on Twitter.

March 14 - Avengers: Endgame trailer features a glimmer of hope in Captain Marvel

Marvel has released the first official trailer for Avengers: Endgame, and while it continues to paint a dire picture, there's the faintest glimmer of hope: Captain Marvel.

It seems that now that her solo movie has been released, Marvel has no problem revealing that, yes, she will be joining the fight come April 26. I guess you don't have to watch that post-credits scene in Captain Marvel to see her with the Avengers.

Here's how Captain Marvel connects to Avengers: Endgame

Much of the trailer recaps where the Avengers have been and the kind of loss they've encountered. But the thing that makes them heroic is that they persevere. They continue to fight.

In this case, the Avengers aren't content to move on from their defeat and want to undo the astronomical damage done by Thanos. How they're going to achieve that remains unclear, but their new white suits and the Quantum Realm might have something to do with it.

March 7 - Disney shows off new footage to shareholders

With about two months until Avengers: Endgame hits theaters, Disney is starting to unveil more of the movie. At a shareholders meeting on Thursday, the company showed off more footage to those in attendance. Comicbook has the scoop:

According to our source, the footage starts out with the Avengers sitting in the room at the Avengers compound we saw in the first teaser and Captain Marvel (Brie Larson) is in attendance. Nebula (Karen Gillan) mentions that she thinks Thanos would go to "the garden" after he completed his plan.

Captain Marvel speaks up and tells the group they need to go there and use the stones to undo everything. The footage then showed Rocket (Bradley Cooper), Thor (Chris Hemsworth), Nebula, Captain America (Chris Evans), War Machine (Don Cheadle), and Black Widow (Scarlet Johansson) in space. Rocket says something along the lines of, "Who has never been in space before? Raise your hand."

The footage then closes with Rocket warning those who haven't been in space to not puke on his ship.

February 7 - The official synopsis for the movie revealed

As April gets closer, we are finding out more and more details about Avengers: Endgame. We just got a new and somewhat limited TV spot (which you can see below) during the Super Bowl that gave us some new footage of the Avengers and now, thanks to Disney's Australian site, we know the official synopsis for the movie, and it is all about retribution.

Avenger the devastating events of Avengers: Infinity War (2018), the universe is in ruins due to the efforts of the Mad Titan, Thanos. With the help of the remaining allies, the Avengers must assemble once more in order to undo Thanos' actions and restore order to the universe once and for all, no matter what consequences may be in store.

That last part is the most interesting. One of the popular theories surrounding Avengers: Endgame has been who can possibly die. Judging from the last line in the synopsis, death may take a heavy toll as the Avengers take on Thanos and undo the damage he has done.

January 29 - Avengers: Endgame merchandise reveals new "space suits"

Earlier this year, we got a glimpse at some of the original Avengers wearing new "space suits." Now, a new toy leak purports to confirm the sartorial changes coming to the Avengers universe.

Images shared by Stephen Parker on Twitter reveals Thor, Rocket, Valkyrie, and Black Widow all wearing new suits, which will apparently be for time traveling purposes.

The images don't reveal much else—and it's always difficult to ascertain a movie's plot details based on toys. Oftentimes what's included in a toy set isn't what is found in a movie.

All the big details

Avengers: Endgame trailer

Release date and runtime

Avengers: Endgame is set to hit theaters on April 26, 2019. Although an official runtime hasn't been revealed, reports claim the movie could clock in at around three hours.

Avengers: Endgame title reveal

For months, Marvel kept Avengers: Endgame's official title a secret, saying to reveal it would be a spoiler. Turns out, it ended up being titled what everyone expected all along.

The "endgame" in Avengers: Endgame refers to a line spoken by Doctor Strange in Avengers: Infinity War. Before giving the Time Stone to Thanos, he tells Tony Stark, "We're in the endgame now."

The definition of endgame is: the final stage of a game such as chess or bridge, when few pieces or cards remain. With only a few Avengers left and half of the universe gone, the stakes have never been higher.

Avengers: Endgame recap

The MCU began all the way back in 2008, so you may have forgotten what's happened up until now. All you really need to know is that Thanos successfully wiped out half the universe after collecting all six Infinity Stones. He said he did it for the good of all life, as a way to ensure prosperity across the universe.

After Tony Stark's introduction, Marvel spends Phase 1 introducing the founding members of the MCU, including Bruce Banner/Hulk, Natasha Romanoff/Black Widow, Clint Barton/Hawkeye, Thor, and Steve Rogers/Captain America. In 2012, the Avengers team up to take on Loki and a Chitauri invasion of New York. They eat shawarma and call it a day.

In Phase 2, the Infinity Stones start to become a more important part of the narrative. The Guardians of the Galaxy and Ant-Man make their debut, giving Marvel the chance to explore the complexity of the Quantum Realm.

Then, in a mid-credits scene from Avengers: Age of Ultron, Thanos wields an Infinity Gauntlet and vows to personally collect the Infinity Stones, rather than hiring others to do the work for him.

Phase 3 is easily Marvel's most important phase, because it features the most drama, action, and destruction. In Captain America: Civil War, the Avengers become divided over the Sokovia accords, a document that would have given a panel power to control the team. It's this movie we're introduced to Tom Holland's Spider-Man.

Marvel then introduces Doctor Strange and Black Panther, before we finally get to Avengers: Infinity War, where Thanos successfully collects the Infinity Stones and wipes out half the universe. Some of the MCU's biggest characters died, including Spider-Man, Peter Quill, and Black Panther, to name a few.

Avengers: Endgame characters

Not everyone perished from Thanos's snap. In fact, quite a few Avengers survived. Here's a list of who will still be alive when Avengers: Endgame hits theaters.

  • Black Widow
  • Captain America
  • Ant-Man
  • Hawkeye
  • Hulk
  • M'Baku
  • Shuri
  • Rocket Raccoon
  • Nebula
  • Iron Man
  • Okoye
  • Thor
  • Valkyrie
  • Captain Marvel

Avengers: Endgame plot

At this point, very little is know about Avengers: Endgame. About all we do know is that the Avengers have some sort of plan. But what is it?

Over the past several months, there have been numerous theories about how Avengers: Endgame will unfold, from speculation about a cosmic threat to traveling through the Quantum Realm. The thing is, we have no clue what's going to happen.

Based on what we learned in the trailer, we know that whatever Scott Lang has to say to the Avengers, it's very important. Remember, right before Lang went into the Quantum Realm at the end of Ant-Man and the Wasp, Janet Van Dyne warned him to stay away from time vortexes.

Time travel is going to play an important part

We're not sure how Lang was able to escape the Quantum Realm, but Van Dyne's line about time vortexes is likely very important.

Many rumors about Avengers: Endgame claim the remaining Avengers will go back in time and attempt to collect the Infinity Stones before Thanos does. Whether they're successful remains to be seen, but you can bet characters like Spider-Man and Black Panther won't stay dead.

Not to mention Captain Marvel has yet to join the fray. The hero will make her long awaited debut in Captain Marvel in March, before becoming a more important part of the wider MCU. Why else would Nick Fury have paged her at the end of Avengers: Infinity War?
