(Cover) - EN Showbiz - Bryan Cranston found shooting a sex scene with Julia Roberts incredibly "awkward".

The 55-year-old actor and Julia shot a raunchy scene for Larry Crowne, a romantic comedy directed by Tom Hanks. Bryan did not feel very comfortable during filming, as he was the only one in the room nearly stark naked.

"It was probably more awkward for me, because under the sheets, [Julia] was wearing sweatpants and a sweatshirt," said Bryan to Playboy magazine. "Tom kept tugging on her shirt. Aw, Julia, Julia. Come on, we've got to show something. We've got to show a little skin.' And me, I'm just wearing a c*ck sock."

In anticipation of this scene Bryan prepped himself thoroughly. He spent several months getting up to par physically before revealing his naked flesh in front of one of the most beautiful women in the world.

"Before we shot the movie, I went on a diet and bleached my teeth and got one of those spray tans," said Bryan. "I wanted it to seem like we were at least viable as a couple. "

Bryan and Julia's film Larry Crowne is in theatres now. (C) Cover Media
