Zac fell and hurt himself on the set of High School Musical 3: Senior Year , after he had to run around a rotating hallway. Zac had to jump and slide down a revolving school corridor while singing and dancing. He spilled:

‘We had always talked about doing a scene in a revolving setting and then one day I walked in and there was a revolving hallway. It was like a square inside a big hamster wheel. I got there and the crew said, ‘OK, let’s go!’

I was like, ‘I haven’t rehearsed yet guys!’ So Kenny Ortega, the director, told me to rehearse it but also filmed it at the same time. It was crazy! I fell over a few times. At one point it reversed direction and I wasn’t ready, I ate it then!‘
