Zac Efron is convinced he doesn't deserve to be the star of a huge blockbuster yet - because he's still "paying his dues" in Hollywood after shooting to fame in Disney's High School Musical.

The 22-year-old actor, who was previously vying for the lead in the Spider-Man franchise, is desperate to sink his teeth into a meaty role but admits he has yet to earn the respect of movie fans.

He tells Movieline.com, "I have a self-awareness of what is out there: Right now, if I was looking at me from someone else's eyes - like the eyes of the guys who are going to go watch a superhero movie - I can't say that I'd be 'two thumbs up' for me to star in an action movie right now. Why would I be? I haven't done anything to pay those dues yet, I haven't made any movies for those fans yet. I think you have to earn the right to hold a gun. You have to earn the right to shoot web."

However, he's convinced newcomer Andrew Garfield, who has been cast as the new Spider-Man, is better suited for the part.
 
He adds, "He's coming in as an unknown. Andrew Garfield is going to be amazing in that movie because he's got a brand-new, fresh perspective, and to be thrown into that character so quickly, he's going to be able to redefine that brand in a way that we've never seen before. It'll be amazing. You've sort of seen me before."
