Arsenic & Old Lace
Arsenic and Old Lace is a play by American playwright Joseph Kesselring, written in 1939. It has become best known through the film adaptation starring Cary Grant and directed by Frank Capra. The play was directed by Bretaigne Windust, and opened on 10 January 1941. On 25 September 1943, the play moved to the Hudson Theater. It closed there on 17 June 1944 having played 1,444 performances. Of the twelve plays written by Kesselring, Arsenic and Old Lace is the only one to be successful.

The play is a farcical black comedy revolving around Mortimer Brewster, a theatre-hating drama critic who must deal with his crazy, homicidal family and local police in Brooklyn, New York, as he debates whether to go through with his recent promise to marry the woman he loves. His family includes two spinster aunts who have taken to murdering lonely old men by poisoning them with a glass of home-made elderberry wine laced with arsenic, strychnine, and "just a pinch" of cyanide; a brother who believes he is Teddy Roosevelt and digs locks for the Panama Canal in the cellar of the Brewster home (which then serve as graves for the aunts' victims); and a murderous brother who has received plastic surgery performed by an alcoholic accomplice, Dr. Einstein (a character based on real-life gangland surgeon Joseph Moran) to conceal his identity and now looks like horror-film actor Boris Karloff (a self-referential joke, as the part was originally played by Karloff). The film adaptation follows the same basic plot, with a few minor changes. It is customary, after the cast takes several curtain calls, for the final one to finish with the "murder victims" (often well-known local personalities) entering from the basement and joining the cast for the final bow.
