1Hugh Jackman
Hugh Jackman loves WWE, then how come he regrets his appearance on the show? He was involved in a brief storyline in 2011 with Dolph Ziggler and Zack Ryder, and this was supposed to be a part of the marketing campaign for the movie called Real Steal. And this was exactly the problem. Even though the movie had a good idea, it was never appreciated by the audience, and instead of enjoying himself in the ring, Jackman promoted this film.
