The Hangover, excellent movie, once again Las VegaS

Phil (Bradley Cooper), Stu (Ed Helms) and the decidedly off Alan (Galifianakis) are improbable the merely groomsmen to suffer thrown a "spinster" binge in Vegas pro their soon-to-be-betrothed buddy, remembering nothing the subsequently morning of the preceding night's decadence.

But odds are skilled that hardly any have awoken hungover in a trashed Caesar's Palace luxury suite surrounded by wandering chickens, a crying baby in a closet and a very huge tiger belonging to former heavy weight world champion Mike Tyson.

Oh yeah, and the man of the hour (Justin Bartha) has vanished,missing, along with one of Stu's front teeth.

And afterward there's the topic of the hospital bracelet around Phil's wrist and the detail the claim ticket they supply to the hotel valet produces a Vegas law enforcement car.

Pretty much all could be explained during the way of the outrageous hour-and-a-half -- and what isn't will be quite graphically dealt with over the end credits.

The boundary-testing script, officially credited to the prose team of Jon Lucas and Scott Moore ("Ghosts of Girlfriends Past," "Four Christmases") provides the flexible pattern, but it's the straight comic timing of director Phillips and his terrific cast that's ultimately in charge for "The Hangover's" lasting effect.

And though the performances of de-facto leading guy Cooper, Helms (Andy Bernard on "The Office") and Bartha are uniformly easy going, the film serves gonzo Galifianakis much in the same way Will Ferrell broken out after his fearless curve in "Old School."

Furthermore along for the noticeably well-shot (by Lawrence Sher) raucous trip is Heather Graham as a beautifully disposed pole performer whom Helms has apparently married, and Ken Jeong ("Pineapple Express") as the certifiably unhinged, vengeance-seeking Mr. Chow.

Last but certainly not least, there's Mike Tyson, performing a soon-to-be-immortal rendition of Phil Collins' "In the Air Tonight," accompanying himself on air drums.
