Robert Downey Jr. was not first choice to star in 'Iron Man'. The 43-year-old actor had to beg the film's director Jon Favreau to give him the lead role of billionaire weapons developer Tony Stark in the Hollywood blockbuster.

He said: "I thought I would be perfect for the part. But they weren't necessarily thinking of me right away."

Gwyneth Paltrow's scenes with her 'Iron Man' co-star Robert Downey Jr. were "sexually charged".

The 35-year-old actress - who has two children with her Coldplay frontman husband Chris Martin - admits she enjoyed the on-screen chemistry she had with Robert.

Robert Downey Jr. says settling down has been key to his Hollywood comeback.

The 'Iron Man' star revealed his marriage to Susan Levin is the secret to a happy life, and leaving his wild past behind has made this his best year yet.
