Ashley Tisdale talks about doing it again and again at different angles in front of lots of people.

Kissing of course. What were you thinking, you pervert?
People:
"The director [Stephen Herek] is so much fun to work with, he's done so many movies with Angelina Jolie, Kiefer Sutherland, Keanu Reeves," Tisdale says. "[But] I do a couple kiss scenes. I was really uncomfortable, not used to it. ... I was like, 'This is so weird.' " The problem is, she says, "You have so many people watching you. I had done it on my TV shows, but usually it's so different from a movie. You have to do it over and over and over, and every different angle."
