'Iron Man' debuted in Hollywood tonight.

GWYNETH PALTROW hit the red carpet at the historic Grauman's Chinese Theatre on Wednesday night for the West Coast premiere of her new film, 'Iron Man.'

The hot mama has been touring the world along with her castmates from the super hero pic, attending screenings in New York, London and Berlin. ROBERT DOWNEY JR., TERRENCE HOWARD, JEFF BRIDGES and director JON FAVREAU also came out for the big night.

In the film, Downey plays Tony Stark, a billionaire industrialist and genius inventor whose captivity by insurgents motivates him to build a suit of armor to escape. Once free, he uncovers a nefarious plot with global implications and fine-tunes the high-tech suit to protect the world as Iron Man!
