Michael Bay on Dwayne Johnson

ET was with director Michael Bay at the Los Angeles premiere of his new movie Pain and Gain, and he had some encouraging words for Dwayne Johnson, who was home recovering from "minor surgery" due to a wrestling injury.

"It's too bad, but I told him he's getting older and he needs to stop wrestling 300 pound men. He needs to grow up. That's what Wahlberg says. Wahlberg says he's gotta grow up," Bay said jokingly about Johnson's injury sustained during a WWE match.
