Prepare for weeks of Iron Man 2 coverage, starting now.

The blockbuster sequel had a press day in Los Angeles Friday, complete with a photocall of its stars.

Two years ago Gwyneth Paltrow debuted her Tracy Anderson-trained body in a series of minidresses, stealing the night at junkets around the world. This time around, she'll be joined on the red carpet by bombshell Scarlett Johansson, as well as Mickey Rourke and Don Cheadle. Cheadle replaces Terrence Howard.

And Robert Downey Jr, in sneakers no less.
