"Extra" talked with actor Robert Downey Jr. at the L.A. premiere of "The Hangover 2," where we asked him if he'd ever do a film with his pal, Johnny Depp.
"That would be a very low-budget venture. My dry cleaning budget is most film budgets at this point," laughed Downey Jr.
The actor's wife, producer Susan Levin, interjected, "I think it would be fun. Gotta find the right thing."
The "Iron Man" star added, "Butch and Sundance... oh no, they did that. I don't know. I'll have to write it, when I retire, after this interview."
Robert Downey Jr. will next be seen in "Sherlock Holmes: A Game of Shadows" in theaters Dec. 16.
