Zac Efron has admitted that he got the jitters while filming an intimate love scene with celebrity crush Heather Graham.

Efron, 25, and Graham, 43, star in the film At Any Price, and according to the former High School Musical star, filming the intimate scene was not as easy as he thought it would be.

According to NY Post, Efron said at a press event for the film: "I've been a fan of Heather's and had a crush on her since I can remember. She's always been the epitome of that perfect girl. I wanted to get it right."

Graham also spoke to the press about filming the love scene. She said both Efron and director Ramin Bahrani admitted that they had never done a sex scene before so were "kind of nervous."

"I thought it was so funny," she said. "I was suddenly this expert."

At Any Price is a film about the business struggles of a farming family and the relationship between a father and his son. The role of the father is played by Dennis Quad while Efron takes on the role of his son.

Efron attended the Tribeca Film Festival April 19 and showed off his surgically repaired right hand at the red carpet. He had broken his hand while shooting a fight scene with Dave Franco.
