THE UNKNOWN MARX BROTHERS is a superb documentary from 1993, which presents a biography of the brothers, while also focusing on rare and unseen clips from the history of their act. Highlights include Harpo’s silent film cameo in TOO MANY KISSES (1926), trailers for THE BIG STORE and DUCK SOUP, their 1931 routine from THE HOUSE THAT SHADOWS BUILT, outtakes from the aborted TV pilot THE DEPUTY SERAPH (1959), and Groucho’s YOU BET YOUR LIFE SERIES, assorted solo TV spots and various home movies.

There are also valuable interviews with family members and co-workers. Lots of great stuff packed into 85 minutes!
