Actor Seth Rogen was so nervous about filming a sex scene with co-star Katherine Heigl in new movie Knocked Up, he decided to take some ill-advised advice from screen legend SIR Sean Connery. Rogen picked up his Connery tip from an episode of TV show Inside The Actor's Studio in which the Scottish actor joked about how to deal with the possibility of an unwanted erection while shooting a love scene. Rogen says, "I got really nervous and I kept thinking, 'What will I do, how do I behave?' And I was watching TV one day and Inside The Actor's Studio was on and Sean Connery was on it and he has a lot of sex scenes. "He was talking about sex scenes and he said, 'Before every sex scene I say to the woman, 'I'm sorry if I get aroused and I'm sorry if I don't.' I thought, 'That's good, I'll use that.' "So we're shooting the scene and we're getting into position. I'm really focusing on not sweating on her, that's my main goal. I say to her, 'Katherine, I'm sorry if I get aroused and I'm sorry if I don't.' "And she looks at me and says, 'Why would you be sorry if you don't get aroused? I don't want you to get aroused.' I realised that's the difference between my and Sean Connery - people kind of want him to get aroused a little. "I should have just said, 'I'm sorry.' And that's it."
