Scarlett Johansson To Replace Robert Downey Jr.?

There have been plenty of rumors lately on Iron Man 4, one of them involving Downey Jr. saying that filmmakers are likely to cast someone younger for upcoming roles in an interview with The Edge.

"The smart money is you have to look at everybody's age," the actor said. "I'll put myself at the top of the list. Sooner or later, they've got to start over and get somebody young. I'm not there with them yet."

Downey Jr. then said that the reason for this is likely because it would relate better to fresh young audiences.

"When you really think about it at the end of the day these films are entertainment largely driven by young folks," the actor said. "There is something very honorable about that."
