The 25-year-old and Stewart performed a raunchy scene in the movie and the actor admits he felt more distracted looking for his cue rather than romantic.
"I've never done a sex scene where it's kind of scary because you think something is going to fall on you! There was a whole stunt set-up with three guys, who do all the explosions and things, all lying under the bed. I spent the whole time looking at them for a signal. It was funny, though," contactmusic.com quoted Pattinson as saying.
