Robert Downey Jr.
The stars of the new comic book spin-off dusted off suits and dresses to hit Leicester Square, with Robert Downey Jr. threatening to steal the limelight from co-star Gwyneth Paltrow with some serious shades.
The movie, based on the comic, sees Downey Jr. playing a scientist who dons a life-saving suit of armour and then pledges to fight crime as superhero Iron Man.
