Dark hilarity ensues as Mortimer discovers his sweet aunts’ hobby: lacing elderberry wine with arsenic! Add in a brother convinced he's Teddy Roosevelt, another on the run with a Boris Karloff lookalike, and madcap chaos spirals out of control.
The role of Aunt Abby Brewster in Arsenic and Old Lace was played by Josephine Hull, who had previously won a Pulitzer Prize for her performance in the stage play.
The film adaptation of Arsenic and Old Lace was filmed in 1941 but not released until 1944 to honor a contractual agreement with the Broadway play.
