Two years after Robert Downey Jr dazzled us all as billionaire inventor Tony Stark, the Iron Man sequel is upon us.
Iron Man 2 sees Downey Jr team up with Gwynneth Paltrow once again for the Marvel superhero movie directed by Jon Favreau.
In it, Stark finds himself at odds with the very people he has been trying to protect, as the US government - aware that he is a superhero - tries to get him to share his weapons with the military.
The cast list reads like a Who's Who of Hollywood A-listers, featuring appearances by Samuel L Jackson, Mickey Rourke and Scarlett Johansson as undercover martial arts expert Black Widow.
Johansson says the pre-filming fitness regime was tough: "It took months of stunt training and weight training and strength training, endurance training - all of that."
Iron Man 2 is out in cinemas across the UK now.
