Teen-idol Zac Efron was left terrified on the set of his new movie 'The Paperboy' by co-star Nicole Kidman's raunchy approach to their sex scenes together.
The former 'High School Musical' star has admitted that he was looking for a project that moved away from his previous image as a clean cut star and wanted a role with more depth.
According to an interview with Black Book magazine the actor admitted that despite his qualms "enjoyed" being seduced by the 'Eyes Wide Shut' actress, 45.
However there was one explicit scene, which also involved co-star John Cusack, that left him actually scared of romping with the screen siren.

Zac's character Jack Jansen watches on as co-star John's character does a sex act in his underwear after being turned on by Nicole's character Charlotte Bless.
The star admitted, "That was the first day of filming and Nicole just completely went for it. She was telling everyone 'I'm bringing my A-game. What do you have?'
"I've never been so scared in my life, but that moment affirmed this movie was everything I set out to do."
So frightening, enjoyable? ASffirming? Sounds like Zac is experiencing grown up sex scenes for the very first time.
