Actor Orlando Bloom felt empowered shooting his first full-frontal nude scene in upcoming crime drama Zulu after previously shying away from baring all on camera.

The Pirates of the Caribbean star admits he has always been weary about showing his manhood onscreen, and only agreed to strip off in his role as a womaniser after hitting the gym hard to make sure he looked his best in his moment of glory.

He tells Elle magazine, "I got in the best shape of my life for that movie."

When asked if disrobing was empowering, he replies, "It was. Dude, it is what it is. It's flesh and bone. It's what we all are."

And once he got used to walking around the set naked, he couldn't help but have a little cheeky fun with his co-workers.

He reveals, "It was quite amusing walking around set and seeing the crew avert their eyes at first. I got so comfortable with it I could brush up behind someone and go, 'Oh, excuse me.'"
