Late Marx Bros. comedy is also probably their best film since A DAY AT THE RACES. A mild parody of the Humphrey Bogart classic, the film really has more to do with the Brothers on the trail of a Nazi war criminal (played by expert comedic foil Sig Ruman) trying to smuggle stolen art out of Casablanca.
The film features some of Groucho's best lines (his scene at the hotel desk with a Mr. and Mrs. Smyth is a highlight), Harpo has some great sight gags (contributed by an uncredited Frank Tashlin), and Chico has a fun piano solo performing "Beer Barrel Polka". Also features the Bert Kalmar-Harry Ruby tune "Who's Sorry Now?"
Directed by Archie Mayo, written by Joseph Fields and and Roland Kibbee. Also starring Charles Drake, Lois Collier, Lisette Verea, Dan Seymour, and others.
