One Body Too Many is a 1944 American comedy-mystery film directed by Frank McDonald, starring Bela Lugosi, Jack Haley and Lyle Talbot. The film was the second comedy featuring Haley to be produced by Pine-Thomas Productions, part of the studio's new direction towards comedy films. The original intention was to hire Boris Karloff for the film's key horror role, but Lugosi was hired instead.

Plot

Mild-mannered insurance salesman Albert L. Tuttle (Jack Haley) visits eccentric millionaire Cyrus J. Rutherford, intent on selling him a $200,000 insurance deal. Instead he finds that Rutherford has recently died and his mansion is now full of relatives who are, according to the will, all bound to remain in the mansion until a glass-domed vault is constructed on the roof to house the deceased millionaire, who was an ardent follower of the stars.
