8 Stars Who Walked Out On WWE WrestleMania

8. Bret Hart (WrestleMania 22)

Nearly a decade after his glittering WWE career ended in the bitterest acrimony, Bret Hart finally accepted his rightful place in the company's Hall of Fame as part of WrestleMania 22's festivities, legitimising the club in the process. It seemed as though 'The Hitman' had at last managed to file away the pain of the past.

Not quite.

Though Hart was more than willing to bask in the adulation of an assembled auditorium, recognised for his incomparable contribution to the business, Calgary's finest wanted absolutely nothing to do with the product itself. Officially, he refused the traditional inductee cameo at 'Mania proper because he feared it might corroborate conspiracy theories that Montreal was a work - particular as Shawn Michaels and Vince McMahon were due to face one another that night, in a weird sort of poetry.

In actuality, Hart knew that if he ran afoul of HBK, he was likely to lamp him. He told Calgary Sun ahead of the event that he'd high-tail if Shawn was at his speech, saying the situation was still "too combustible". Ring on finger and thoroughly honoured, Bret wisely enacted a pre-emptive walkout of the show itself.
