The Mighty Duck once was a master mosher. Seriously. Learning the nitty-gritty of the repossession biz from Stanton's coke addict, Emilio Estevez chases a 1964 Chevy Malibu from outer space in punk auteur Alex Cox's Repo Man. Imagine Travis Bickle traversing the neon graffiti wasteland of early MTV while proclaiming, ''Let's go do some crimes.... Let's go get sushi and not pay.'' EXTRAS In an interview, Harry Dean Stanton explicates nihilism. But we're more stirred by his irascible retorts to the naggy questioner (''Don't you get it?'') and his random, mid-chat ''Row Your Boat'' performance. Commentary by Cox and cast and crew merrily waxes nostalgic about Estevez's on-set behavior ''He liked to run around in his briefs a lot,'' ''Always nice and clean, though'' and boasts film's first use of air bags. So punk rock.
