CBS Films is moving forward quickly on a sequel to the "geriatric Hangover"-style comedy "Last Vegas".
David Diamond and David Weissman have been hired to pen the second installment, taking over from Dan Fogelman who wrote the first, while director Jon Turteltaub is being sought to return for the follow-up.
Michael Douglas, Robert De Niro, Morgan Freeman and Kevin Kline are expected to be back for the sequel in which the quartet return to their old stomping grounds in Brooklyn.
They discover that borough has changed more than a little since the four grew up there. Laurence Mark and Amy Baer will also return as producers.
The first film became a surprise sleeper, nabbing $134 million at the global box-office and proving a strong performer on home video and VOD.
