Hollywood star Zac Efron felt 'mortified' when he got trapped in a theatre seat during the filming of 'High School Musical 3: Senior Year'.

'I don't know how it happened but my foot slipped through a theatre seat during filming and I couldn't get it out,' femalefirst.co.uk quoted Efron as saying.

'It was so funny because they had to take the seat apart to rescue my foot. The cameras had to stop rolling and people were brought on set to unscrew the bottom of the chair. I was mortified,' he added.
