Kevin Klien — and his Lipitor — join the boys in Sin City for an atypical bachelor party

The trailer for "Last Vegas" proves that old dudes can still party.

Billy is getting married, so he invites his longtime buddies to Las Vegas for his bachelor party. Sound like a familiar premise? Did we mention that Billy and his friends are in their 60s (at least)?

Yes, "Last Vegas" is "The Hangover" for senior citizens.

The bachelor (Michael Douglas) and his three best friends, Paddy (Robert De Niro), Archie (Morgan Freeman) and Sam (Kevin Kline) are down to get crazy, just like the old days. Only the old days never looked like this — nor did they include Red Bull and vodkas — much to the retroactive chagrin of Freeman's character.

Billy wants his friends to get in trouble in Sin City. By the looks of the trailer, that shouldn't be a problem.

"Last Vegas" is currently rated "R" for "brief sexual content," but CBS Films is appealing for "PG-13." The comedy comes out Nov. 1.
