Hayden Christensen has admitted that he was "terrified" of filming his sex scene with Jessica Alba in forthcoming movie Awake.

The films focuses on Christensen's character, a man who experiences anaesthetic awareness and can feel the excruciating pain as he undergoes heart surgery.

The actor revealed that he found the love scene even more difficult than shooting a fight scene for Star Wars.

Christensen said: "I was just so nervous. Really nervous. Running around with a lightsaber is really pretend, but when you are put in a situation where the scene you are doing becomes so real, it is terrifying!"
