Zac Efron worried about failure
Zac Efron thought he could "fall flat on his face" in his new role.
The 22-year-old actor - who achieved worldwide fame starring as Troy Bolton in the 'High School Musical' movies - admitted prior to appearing as the titular character in new movie 'The Death and Life of Charlie St. Cloud', he had only "scratched the surface" of dramatic roles, and so was ready for a new challenge.
He explained: "I was looking for a dramatic role for a long time and wanted to see how it is to star in a drama. So far I've only scratched the surface of what it means to be a good actor.
"It was exactly what I was looking for. I wanted to learn something new and knew it wouldn't come to me easily. I knew I had to work hard for this film and that there was a chance of me falling flat on my face. Since then I've got even more admiration for people who take risks and don't always stay on the safe side."
The hunky star revealed in addition to the part posing a challenge, the "romantic" side of the script appealed to him.
He added to German newspaper Hamburger Abendblatt: "The story fascinated me when I read the script. Apart from that the film has a romantic side to it - which the fans surely will appreciate - and supernatural elements, which are pretty cool. I also liked how the film doesn't fit into just one genre.
"It's dramatic, different and certainly not something people expected from me."
