Yesterday, we told you that Michael Douglas (Wall Street) will star in the upcoming film Last Vegas, which will be helmed by National Treasure‘s Jon Turteltaub. New rumors are surfacing today that Robert De Niro (The Godfather Part II) may be joining Douglas!

Vulture states Christopher Walken may also join the film as well:

Vulture hears exclusively that the studio is in the process of making a deal with Robert De Niro to star opposite Douglas in a script by Dan Fogelman, screenwriter of last summer’s sleeper hit Crazy Stupid Love. We hear that De Niro and Douglas would play oldsters who both fall for the same “girl.” The film, to be directed by Jon Turteltaub (National Treasure), is essentially The Hangover for the olds — four men of a certain age gather in Vegas for a bachelor party.

We also hear that talks continue with Christopher Walken to co-star, but that the studio plans to try to make a deal with De Niro first before ironing out a pact with the high-haired Walken.

What do you think about De Niro potentially joining the film?
