In a recent interview with LA Times, Iron Man 2 director Jon Favreau went into depth as he talked about Stark Expo in the film. The Expo has a very important part in the story, it is the place that contains many themes from the story such as family secrets and complicated legacies. So how does this tie in with Captain America? I guess we'll throw up a spoiler alert just in case.
Favraeu revealed that the history of the Stark Expo will echo in the other Marvel films, he explains,
It does figure in to the other films because in the Captain America movie you're going to see the early one, which I think is a lot of fun. They're going to have a reference to Tony's father, Howard Stark, played by John Slattery, and his earlier Expo. But I don't want to say more than that.
The fact that he doesn't want to say anymore than that tells me that there is a lot more to how the films will tie together. He also gives a little history on the Expo saying,
The Expo dates back to the 1930s, but the last one was in 1974 when Tony's father was still alive and Tony was just a kid. Now Tony is reintroducing this concept of the Expo at the start of the film and it's presented a part of peace dividend -- now that Iron Man is keeping the world 'safer,' this is Tony's way of turning guns to butter and changing the conversation about the future.
Iron Man 2 is scheduled to come out on May 7th and we're all pretty freakin excited to see it, as I'm sure you are as well.
