It's no secret that both "Iron Man" and "Iron Man 2" relied heavily on improv from their cast of talented actors, but did you know that going the ad-lib route can mean some very cool, fan-friendly bonuses?
Take, for example, the sheer amount of extra footage created by "Iron Man 2" improvisation. According to director Jon Favreau, it amounts to around 30 minutes of alternate scenes and extra footage — all of which will likely be included on the "Iron Man 2" DVD.
"I think it's about a half an hour of that stuff," Favreau told MTV News. "You change things... There's a lot of latitude in post-production on this kind of movie."
"Iron Man 2" hits theaters May 7. Let us know what you think in the comment section or on Twitter!
