The films--packaged handsomely with a booklet--are essential Marx Brothers, their first five films made from 1929 to 1933. The least timeless is their first, The Cocoanuts, based on their Broadway hit. The film--one of the first full talkies--takes place in a hotel with owner Groucho out to grab every dollar. Animal Crackers is the brothers' first classic, a lickety-split comedy about an art theft being investigated by Groucho's alter-image, Captain Spaulding. For introducing youngsters to the work of Marx, Monkey Business is the best way. The shenanigans start right at the start as the brothers stowaway on a luxury liner. It's their first film that wasn't based on a play, as they endeavored to find new material. Horse Feathers gave them more fertile ground plus a sure-fire Hollywood director at the helm (Norman McLeoad). Their fantasia of college life includes the riotous football-game finale. Music, always a key part of their plays and films is given more weight here and includes Groucho's theme, "I'm Against It." Music is again key as the musicals of the era are spoofed in the brothers' undisputed masterpiece, Duck Soup. From a land called Fredonia, Groucho plays a slapdash ruler who rewrites the rules of governing, leading to a most memorable war with Sylvania (so war gets lampooned. too). Duck Soup also boasts the most famous Marx brothers sketch: Groucho trying to fool his mirror. --Doug Thomas
