Deadpool contained all sorts of CGI tweaking, whether it was the eyes on Deadpool’s mask, background extensions, or apparently, helping Ryan Reynolds’ skin look as disgusting as possible. Take a look at how some of the film’s sequences came to light in a new VFX breakdown from Rodeo.

As well as the video above, Rodeo’s site includes an extensive interview with some of the VFX supervisors and artists who worked on the film, elaborating on how they brought sequences like the Helicarrier fight and the initial fiery conflict between Wade and Francis. It’s well worth a read—and there’s a few neat sliders letting you look at before-and-after versions of shots from the film. Check out a few below.
