Zac Efron was devastated when filming wrapped on High School Musical 3: Senior Year, because his fellow cast members are like family to the actor.

The 20-year-old has starred in all three films of the Disney franchise, but has ruled out appearing in a fourth edition, which is in the pipeline.

And leaving the set for the final time was a hard day for him.

Efron tells Wenn, "It was very emotional. It's like a family that we've built.

"Throughout all of our other ventures - music or television or other movies - we've always had High School Musical to come back to."
