Captain America has just released a new tv spot on the super bowl. I must say I was thoroughly impressed with the skinny CGI effects. I’m going to break down how I think it was done. I say this alot with effects that change a character’s physical appearance, but I believe they are using something similar to Benjamin Button special effects techniques. Obviously, they cast a really scrawny actor for the role of the body and matched Chris Evans head on it. They did this in Benjamin Button, except they replaced the stand in’s head with a cgi head. Here, I believe the effects company used an actual blue screened Chris Evans head. I’ll go through my theories on this and why in a minute. This technique is nothing new, they do it to replace stunt mens heads all the time. The difference there is that stunt men are matched to the actor as much as possible in height, weight and look. In Captain America, Chris Evans is trying to be made to look scrawny for his before super hero look.
It almost looks like they are warping his face slightly to match the other actor’s head or body. What I can’t tell if that is all of Chris Evans head and it is warped, or if it is just face on another actor’s head. If you want to go really out of the way, the head could be entirely CGI except for the facial area. That way it would be easier to match move his actual face to it. Again, I don’t know the actual techniques that were used, but I’m using my best 3d guessing game here. Here’s a few more shots from the trailer.
They actually did a spectacular job with these effects and this is just the TV Spot.
Finally, I’ve saved the best for last. The absolutely best screenshot of a scrawny, skinny, Chris Evans in the Captain America movie. Him crawling under the barbed wire is pretty amazing. Everything about it is very convincing and Evans sells the shot pretty good too. Can’t wait for Captain America: The First Avenger to come out.
