Mabel's Blunder, written and directed by Mabel Normand for Mack Sennett's Keystone Film Company and released October 1914 was Normand's 172nd film although she had only started in the business 4 1/2 years earlier at Vitagraph Co. This film is Public Domain.
Harry (Harry McCoy), the boss's son and Mabel (Mabel Normand), the office girl are secretly engaged but the boss, Harry's father, not knowing of the engagement, is also trying to woo Mabel. A mystery woman (Eva Nelson), arrives to visit Harry and Mabel thinks she is being two-timed when she peeps through a keyhole and sees Harry and Eva embrace. As Harry and Eva leave for a party, Mabel plots to trade identities with her brother (Al St. John), who had arrived to chauffeur Harry to the party. Mabel, now disguised as her brother the chauffeur drives her boyfriend Harry and Eva to the party and she is mad and cussing all the way. Meanwhile poor Mabel's brother, now wearing Mabel's clothes, is spirited away to the party by Harry's father thinking he finally has Mabel all to himself. The plot comes unwound in typical Keystone fashion. We discover the identity of the mystery woman in part II. Charley Chase also has a small part in this film as Harry's friend.
