How did they create Skinny Steve for Captain America: The First Avenger?

I joined the process at the start of the pre-production tests as the template for Skinny Steve Rogers. Working with effects supervisor Christopher Townsend and his team, they started out with a few different technologies, one of which was cgi head replacement. The idea was that Chris Evans (Captain America) would perform the movement and dialogue, then I mimic his movement to a sequence of beeps to hit the same marks. This was abandoned after a few tries, as we found it was quite a tricky and time consuming way to go about it without much room for error, and Chris wasn't too keen about giving up the performance of Skinny Steve. As he wisely puts it, "I think in the beginning of the movie is when you need to fall in love with Steve. I didn't feel comfortable with someone else doing the body, body is a big piece of the acting puzzle." The process was very helpful though in deciding that the best way to go was to only use a double for reference and head replacement when the character was not moving.

While production was under way, I was brought back in as a Skinny Steve stand-in for the effect shot on set and Leander Deeny was the head replacement body double if there was limited motion.

In the final film, the performance is about 80% Chris Evans shrunk down via cgi. When he had to interact with other characters in the scene, they had to either lower him or raise the other actors on apple boxes or elevated walkways to make skinny Steve shorter in comparison. For close-ups, the other actors had
to look at marks on his chin that represented where his eyes would be after the
shrinking process, and he had to look at marks on the tops of the actor's head
to represent their eyes.

You played the god Hermes in Wrath of the Titans?

Yes. The scene in question, which also featured Apollo and Athena, has Zeus being driven before Hades and Ares through the underworld. Zeus Looks up and is horrified to see his missing children. They've been fused with the rock - arms and legs sticking out in tortured poses. Their heads hang limp, their bodies emaciated.

Unfortunately it didn't make it into the theatrical release of the film. It does however appear in the deleted scenes section of the Blu Ray under the title "Zeus is Led Past Missing Olympians".

There was also another scene filmed in the underworld as the ceiling falls down around the dying Olympians while Perseus, Agenor and Andromeda are making their escape. This doesn't appear or feature on any release of the film.
