The one fair criticism leveled at the deliriously ribald Wedding Crashers is that it just didn’t know when to quit — that overlong montage to the Isley Brothers’ ”Shout,” a protracted third act — so an ”uncorked” edition that passes the two-hour mark might be too much of a good thing. The seven new scenes have a pretty high batting average, though, and the best (Vince Vaughn running into a former conquest at a wedding; Vaughn having an unwelcome assignation with Grandma; Vaughn discussing self-pleasure with the right reverend Henry Gibson) add to Wedding Crashers‘ ramshackle good vibe. Note that all of those moments involve Vince Vaughn rather than Owen Wilson; note that this is not a coincidence. EXTRAS The regular R-rated theatrical cut is here, as well as four deleted scenes with commentary, a soundtrack listing that links to selected scenes in the film, and 24 on-screen pages of ”Rules of Wedding Crashing.” (”The unmarried female rabbi — is she fair game? Of course she is.”) Of the two commentary tracks, the one with Vaughn and Wilson is amusing, smug, and disposable. Director David Dobkin, by contrast, turns out to be a regular Chatty Cathy, and his insights are alternately spot-on (he calls the film ”a coming-of-age story for 35-year-old men”) and sweetly pompous (”I love complex tonalities in a movie”).
