Jeff Krulik has attracted a healthy cult following with pop-anthropology exercises like Heavy Metal Parking Lot (1986) and Neil Diamond Parking Lot (1998). I’ve never been very taken with his winking celebrations of American kitsch, but this 50-minute video documentary is another story. Shot at a reunion of the 42nd Rainbow Infantry Division, it focuses on Richard Marowitz, a Jewish-American soldier who helped to liberate Dachau and came home with a singular war trophy: a silk top hat abandoned in a Munich closet by the Fuhrer himself. Krulik offsets the veterans’ sobering reminiscences with all manner of goofy anti-Nazi propaganda (featuring, among others, Bing Crosby, Jack Benny, and the Three Stooges); the delicate blend of epic tragedy and inane pop culture borders on the elegiac.
