Sure, Leonardo DiCaprio is one of the biggest stars in the world, but there was a time when he was just a cute sitcom kid trying to transition into meatier film roles, like with 1993's "What's Eating Gilbert Grape."

And it probably didn't help to have his older, more successful co-star be such a jerk to him. "I tortured him. I really did," Johnny Depp told an audience at the Santa Barbara Film Festival this weekend. "It was kind of a dark period. [I'd say], 'No, I will not give you a drag of my cigarette while you hide from your mother again, Leo.'"

And you see what that led to? DiCaprio vaping all the way through the SAG Awards. Good work, Depp.
