Before the world of sports entertainment began producing A-list stars for the big screen, pro wrestlers mostly starred in B-movies or had supporting roles in Adam Sandler flicks. That all changed when Dwayne Johnson decided to bring his undeniable presence to the big screen, and no one is happier about it than John Cena.

Cena was critical of the former WWE Champion's decision to leave for Hollywood, but he changed his tune when he became an A-list actor in his own right. These days, Cena is more empathetic toward Johnson's career, and he even credits the man formerly known as The Rock for paving the way for his own success.

In an interview with GQ, Cena revealed that Johnson's success has helped change the perception of pro wrestlers as actors. He even went on to recall how Johnson helped him land a role in "Trainwreck," where he advised him to just be himself.
