Rarely shown in the U.S. these days, this 1941 film of the wildly deconstructive stage farce with Ole Olsen and Chic Johnson is still regarded as a classic in Europe, and it lives up to its reputation. The credit sequence establishes the wartime mood with its vision of hell as a munitions factory (where demons preside over the packaging of Canned Guy and Canned Gal), which is shortly revealed as a movie soundstage, the first of many metafictional gags. Very belatedly the movie gets around to telling a spare musical-comedy story (with swell numbers by Martha Raye and the jazz duo of Slim Gaillard and "Slam" Stewart, and some very acrobatic jitterbugging), but the main bill of fare is manic nonsense that almost makes the Marx Brothers look sober. H.C. Potter directed; with Mischa Auer, Shemp Howard, and Elisha Cook Jr. 84 min. Sun 1/23, 7 PM, Univ. of Chicago Doc Films.
