Written by Bert Kalmar and Harry Ruby for the 1932 comedic masterpiece "Horse Feathers," "Ev'ryone Says 'I Love You'" provides the perfect crutch for the Marx Brothers' madcap humor. First sung in the picture by the more sedate Zeppo Marx, who plays a floundering college student in love, the song takes on increasingly zany interpretations when sung by Chico and Groucho Marx as all three vie for the same girl. Harpo finally whistles the tune to the love of his life - his horse! A boisterous attack on authority and a parody of higher of education, "Horse Feathers" is the Marx Brothers' fourth movie. Following their successes in "The Cocoanuts" (1929) and "Animal Crackers" (1930), both filmed at Paramount's Astoria Studio, the comedic team moved to Paramount Studios in Hollywood. One of their first West Coast movies, Horse Feathers was an immediate success. In a testament to the Marx Brothers' contribution to film history, Woody Allen titled his 1996 film "Everybody Says I Love You" after the now-famous song from "Horse Feathers." Paying homage to the American musical of the 1930s, Allen's film features ordinary actors singing some of the best-loved tunes of the that era, including the title song.
