Dwayne “The Rock” Johnson recently signed a contract to film an upcoming movie titled San Andreas. Filming for the movie is set to begin in April of 2014, which is the same month of WrestleMania 30. This may very well be a sign that Johnson will not be appearing at the pay-per-view. Though, nothing is definitive.
Even though filming for San Andreas could occur after WrestleMania 30, film producers would likely not want to take a chance on The Rock getting injured during the event. Last year, after suffering an injury during his WrestleMania 29 match with John Cena, Rock had to begin filming another one of his projects just weeks later.
