Jon Favreau isn't convinced that the plan to start filming Iron Man 2 as early as this March is a good idea. Responding to Terrence Howard's statement about when filming would begin, Favreau answered a question on a MySpace forum where he expressed his concerns about the release date.

It's been five weeks since the one and only phone call my reps have gotten from Marvel. I know their hands are full with the The Incredible Hulk and I'm sure they will get into it shortly, as they tell me they intend to. I ran into the Marvel guys at the The Incredible Hulk premiere and everyone sounded eager to get to work on Iron Man 2.

I am concerned, however, about the announced release date of April 2010. Neither Robert nor I were consulted about this and we are both concerned about how realistic the date is in light of the fact that we have no script, story or even writers hired yet. This genre of movie is best when it is done thoughtfully and with plenty of preparation. It might be better to follow the Batman Begins/The Dark Knight, X-Men/X2: X-Men United three year release pattern than to scramble for a date. It is difficult because there are no Marvel 09 releases and they need product, but I also think we owe it to the fans to have a great version of IM2 and, at this point, we would have less time to make it than the first one.

In addition to that statement, Favreau answered many other questions (including denying that there was ever any plan for Hillary Swank to make a cameo in the film) from the fans. If you'd like to join the conversation CLICK HERE.
