Vince Vaughn is set to star in an untitled David O. Russell-directed and -written comedy, according to the Hollywood Reporter.
Vaughn will play the wiseass host of a radio call-in show he runs with his producer girlfriend. His life is turned upside down when he starts taking on the qualities of his neurotic callers.
"I was so tickled by it, I thought, Gee, maybe it would be fun to make this," Russell said.
Russell, who met Vaughn for the first time at the Festival de Cannes in 1996 when the director was promoting his "Flirting With Disaster," said the actor follows in the tradition of a certain type of humor.
"There's Walter Matthau, there's Bill Murray and there's Vince Vaughn. I think it's a certain lineage of comedians," Russell said. "The guys are funny being who they are. They don't put on some kind of broad character, usually. It's very natural, it's very authentic. It's maybe a little bit depressed, but in their depression or their groundedness, they're funny. It's not like they're a drag to be around; they're funny in their depression in some way. I would say Vince is a bit more manically entertaining."
