Robert De Niro and Christopher Walken are both in talks to star opposite Michael Douglas in the comedy Last Vegas, says Vulture.

The film centres on four men who hit up Vegas for a bit of a shindig. De Niro and Douglas will play two old dudes vying for the affections of the same lady. The fourth older fella is yet to be cast, but surely if it's a big enough role someone would give Jack Nicholson or Clint Eastwood a shout? Great cast regardless.

Dan Fogelman is writing and Jon Turteltaub directs. The former penned the very enjoyable Crazy, Stupid, Love the latter directed the likes of National Treasure.
