Robert Pattinson became an actor for "the pretty girls".

The screen heartthrob - who has been dating actress Kristen Stewart since meeting her on the 'Twilight' set - admits his initial interest in drama was fuelled by the possibility of meeting women as well as a love of the art form.

He said: "I suppose it was a variety of things . the pretty girls? There was a theatre around the corner from my house. I guess it was something I always wanted to do, but I thought it was pretty pretentious; I didn't mind the kids that were acting at school but I wanted to do it secretly outside the school.

"I just liked the environment; I worked backstage for about three years and just watched everything and then I did a couple of plays and I got an agent from one of the plays, totally randomly."

The 24-year-old actor can currently be seen starring opposite Reese Witherspoon in new romantic movie 'Water For Elephants' and he has admitted his favourite thing about the shoot was working with all the animals on set.

Robert - who plays a vet, Jacob Jankowski, who falls in love with Reese's character, circus performer Marlena Rosenbluth, in the movie - told The Independent newspaper: "In a lot of ways, I prefer working with animals and kids more than grown up actors. If someone else isn't acting in the scene, it's easier to not act. It seems like actors become almost competitive which works sometimes, but a lot of times my brain doesn't want to do that. If I feel like I can't beat the other actor, I just don't do anything."
