Don't know if this is the right place to ask this, but I'm wondering how they created the hole in Robert Downey Jr.'s chest so they can put the reactor there? Here is the video "Iron Man: Behind the Scenes" where you can see the actual hole; this is behind the scenes so no CG.

This question came from our site for science fiction and fantasy enthusiasts.

I don't know this for certain, but the way he's slouched in the chair and the way the skin sits, I always assumed that he had a sort of prosthetic chest and he was actually deeper in the chair than he appears to be. – phantom42 May 13 '13 at 19:25
@JohnO many film-makers prefer physical effects, even if it's for mainly emotional reasons, and on a film with a budget like Iron Man's this kind of stuff is a drop in an ocean. Also, I think you're overestimating how much it costs. – evilsoup May 14 '13 at 9:11

This was done using a prosthetic chest on his real chest (make sure to sing that to the tune of "We Want A Rock" by They Might Be Giants).

Skip to 2 minutes in for an explanation.

But to sum up: RDJ is actually sitting inside the chair you see. The chest is a sculpted prosthetic laying above him.

+1 for the TMBG reference. Oh, and for the answer as well. :) – Avner Shahar-Kashtan May 13 '13 at 20:19
All that goo and no rubber gloves? No thanks. – Major Stackings May 13 '13 at 22:16
That's an awesome video. Cheers. – Nobby May 14 '13 at 12:54
+1: excellent find! – wallyk May 14 '13 at 18:30
You can see Downey sitting under the prosthetics at 2:13 in the video in the question. – Michael Itzoe May 15 '13 at 18:43

This is easy, they showed it on youtube. They first created a prosthetic chest over his real chest and spray tanned it to match his original skin tone. Then they put in his "heart" so it would look like it's actually a hole in his chest while his actual chest is underneath it.
