The last of Bud Abbott and Lou Costello's three MGM features, Abbott & Costello in Hollywood is a loose remake of Buster Keaton's Free and Easy. Bud and Lou play a pair of Tinseltown barbers who dream of becoming high-priced showbiz agents. Their first clients are Frances Rafferty and Robert Stanton, whose careers may be over before they begin when A&C manage to antagonize powerful producer Donald MacBride and stuck-up film star Carleton Young. The plot serves only as a clothesline upon which to hang several sidesplitting comedy routines: Abbott teaching Costello how to give a shave, Lou vainly trying to get a good night's sleep, a "stunt man" bit involving the tremulous Costello and hulking Mike Mazurki, and a wild roller-coaster finale. MGM contractees Lucille Ball, Jackie "Butch" Jenkins, Preston S. Foster and Robert Z. Leonard make guest appearances.
