Joseph Gordon-Levitt will preside over the Comedy Central roast of Bruce Willis, which is to be taped at the Hollywood Palladium in Los Angeles July 14.
A teaser Thursday shows Willis engaged in an insult smackdown with comedian Jeffrey Ross, a Comedy Central roast fixture.
Gordon-Levitt and Willis co-starred in the 2012 sci-fi movie "Looper."
"I've looked up to Bruce my whole life. I was genuinely honored to work alongside him and, in essence, PLAY him when we made 'Looper' together," Gordon-Levitt, 37, said in a statement.
Willis, 63, is known for his performances in the "Die Hard" and "Look Who's Talking" film franchises, as well as the TV show "Moonlighting."
His other big-screen credits include "Pulp Fiction," "Death Becomes Her," "12 Monkeys," "The Sixth Sense" and "Armageddon."
