Jon Favreau continues to update us with news about the rehearsals for Iron Man 2 via his account on Twitter. While the reports aren't very in-depth (and how could they be with a 140-character limit?), they're still nice glimpses into the production.

Here's what Favreau had to say on March 24th about working with three of the principals from the film:

@jon_favreau Great rehearsal today with Gwyneth, RDJ and Don Cheadle.

Then on March 26, Favreau wrote:

Favreau also offered up a picture of Rockwell. CLICK HERE to check it out.
