Jon Favreau has updated his Twit­ter account to announce the Iron Man 2 shoot­ing sta­tus (we’re on Twit­ter too),

Rehearsals began today on Iron Man 2. Three weeks from shoot­ing and my life is no longer my own. I for­got how over­whelm­ing this process is.

Mean­while, AICN’s Capone has caught up with Favreau to ques­tion him about the recent spate of cast­ing announce­ments, no more big sur­prises coming:

Capone: There has been a lot of IRON MAN 2 news fly­ing around in the last few days. What’s true? What’s not?

Jon Favreau: I can’t con­firm any cast­ing stuff because there have been no announce­ments made, but let me say that the peo­ple that have deals that should all be final­ized in our cast this week, I should hope…it’s a dif­fer­ent process being that Mar­vel is not a big stu­dio and they don’t really have the infra­struc­ture to get things out there; it’s not as stream­lined as a stu­dio, so I apol­o­gize to the fans for not being able to say things as quickly as pos­si­ble. But they really want to have legal pro­tec­tions and not offi­cially say things until every­thing is done. But, I’m very excited about the peo­ple that we have. There are no big sur­prises in cast­ing com­ing that I can fore­see [laughs]. It’s going to be a really, really good group of peo­ple and a story that takes advan­tage of our cast but is in inun­dated and doesn’t get too com­plex because of the num­ber of new peo­ple that we’re adding, which is always a tar pit for these super­hero movies, you always have to make sure that you add the char­ac­ters in a smart way.

Capone: Are you qui­etly relieved that Samuel L. Jack­son has signed on to play Nick Fury for a bil­lion movies or some­thing like that?

JF: [laughs] I wasn’t wor­ried that Sam sign­ing a nine-picture deal was going to hold up my movie, no. That would have been really bizarre if that had happened.
