I didn’t really notice it at the time, but there was a surprising amount of VFX used in Deadpool. Atomic Fiction posted a video to Vimeo this week, breaking down the movie’s opening freeway sequence. Turns out, pretty much the entire scene was CG.

It’s crazy how well the filmmakers and engineers seamlessly blend real humans with computer generated graphics. I figured a healthy dose of VFX was used during the freeway sequence, but I didn’t think it was used to such an extent—not that that’s a particularly bad thing. If you can’t really tell, then the artists and filmmakers have done their job.

If you haven’t seen Deadpool yet, the video above will spoil what is arguably the best action scene in the movie. If you have seen it, well, you’ll be surprised at not only how cleverly the sequence is shot, but how Atomic Fiction is able to create such convincing CG.
