Two "private eye school" graduates (Bud Abbott and Lou Costello) are hired by a boxer who's been framed for murder by a crooked promoter, but it takes a doctor's invisibility serum and a turn in the ring by Lou to bring the crooks to justice in "Abbott and Costello Meet the Invisible Man" (1951). Arthur Franz, Sheldon Leonard also star. And the boys are American cops working in early-1900s London who find themselves in the middle of a madcap melee after getting mixed up with a mad medico (Boris Karloff) and his monstrous alter ego in "Abbott and Costello Meet Dr. Jekyll and Mr. Hyde" (1953), with Craig Stevens and Helen Westcott. Two-disc set also includes "Abbott and Costello Meet Frankenstein" and "Abbott and Costello Meet the Mummy." 5 1/2 hrs. total.
