I know some of you are likely to cry "Spoiler!" here, but stick with me, folks — this post is fairly spoiler-free for anyone who's seen the first "Iron Man" and has been following along with our "Iron Man 2" coverage thus far.

After making a nice little cameo in 2008's "Iron Man," Captain America's shield returns for yet another appearance in Tony Stark's workshop during a key scene in "Iron Man 2." While we're going to leave out the details surrounding its cameo, we did make sure to get some thoughts from director Jon Favreau about the iconic shield's place in the "Iron Man" universe — and why it popped up in Tony's workshop to begin with.





"We introduced Captain America's shield briefly in one shot in the last film," Favreau told MTV News. "An ILM artist put it in there as a joke to us for our cinesync sessions, when we're approving visual effects."

"They got a laugh out of it, and I said, 'Leave it in, that's pretty cool — let's see if anybody sees it,'" he explained. "Of course, everybody saw it — so now it really was in his room, so we had figure out how to deal with the reality that the shield was in his workshop."

As for why it's there, Favreau wouldn't divulge any information about the conversations he's had with the filmmakers behind the other Marvel movies — except to say that they've had them.

"We've talked about it," he said. "Let's see what ['Captain America' director] Joe Johnston does."

Way back in September 2008, we speculated about the role Tony Stark's father, Howard, would play in the "Captain America" plot — possibly as the inventor of the super-soldier serum that turns Steve Rogers into the Marvel hero. Favreau later confirmed that Howard Stark would appear in Johnston's "Captain America"

"Part of the history of the Stark family is the super-soldier program," he said.
