The Bank Dick (1940)
The Bank Dick (released as The Bank Detective in the United Kingdom) is a 1940 comedy film. Set in Lompoc, California, W. C. Fields plays a character named Egbert Sousé who trips a bank robber and ends up a security guard as a result. The character is a drunk who must repeatedly remind people in exasperation that his name is pronounced "Sousé – accent grave over the 'e'!", because people keep calling him "Souse" (slang for drunkard). In addition to bank and family scenes, it features Fields pretending to be a film director and ends in a chaotic car chase. The Bank Dick is considered a classic of his work, incorporating his usual persona as a drunken henpecked husband with a shrewish wife, disapproving mother-in-law, and savage children.
