Joel Kinnaman injured a muscle in his leg while shooting Robocop.

The 34-year-old actor - who plays cop Alex Murphy who is turned into a cyborg law enforcement officer in the movie - didn't sustain any serious injuries while shooting the action-packed science fiction film and the only ailment he did suffer was a minor muscular strain.

When asked if he had gotten injured at any point during the shoot, Joel told BANG Showbiz, "I pulled my hamstring one day, I did it when I was running."

Kinnaman appears in the movie with a stellar cast, which includes Abbie Cornish, Samuel L. Jackson and Michael Keaton. But there was one actor who Kinnaman enjoyed working with more than anyone else: "Working with Gary Oldman was one of the great experiences of my life, he's an incredible actor and also a wonderful man. I was extremely happy [to get the role], I worked hard to get it. I had to audition three times and finally I was able to convince Dr. Padilha [director] that I was the right guy." Kinnaman was joined on the special blue carpet at the event yesterday evening by his co-stars Oldman and Cornish and the film's director Jose Padilha.
