As creaky as an arthritic hip, “Last Vegas” does for four leading stars of the ’70s and ’80s what movies like “Tough Guys” and “Grumpy Old Men” did for survivors of Hollywood’s storied Golden Age: It lets them show they can still throw a punch, bust a move and get it on, and that they’re not quite ready for the Motion Picture Home just yet.
“Last Vegas” scribe Dan Fogelman (who wrote the monumentally smarter and shrewder “Crazy, Stupid, Love”) sticks to the lowest common denominator as he contrives to get four childhood friends together in Sin City for the bachelor party of the last unmarried man among them.
He’s Billy, played by a blow-dried, spray-tanned Michael Douglas in what feels like a watered-down version of the actor’s magnificent aging lothario from 2009’s “Solitary Man.” When Billy impulsively proposes to his strapping 31-year-old girlfriend (while delivering a friend’s eulogy, no less), best bud Sam (Kevin Kline) suggests a boys’ weekend in Vegas, and the rest of this white-haired wolf pack is soon to follow.
Back when they were kids on the streets of Brooklyn, Billy and his pals were known as the Flatbush Four, though now they’re mainly just flat and bushed. In addition to Sam, there’s stroke survivor Archie (Morgan Freeman, essentially reprising his “Bucket List” character) and surly widower Paddy (Robert De Niro), who hasn’t forgiven Billy for skipping out on his wife’s funeral (she was their shared childhood sweetheart).
