Premise: Arsenic and Old Lace (film) . Boris Karloff played Jonathan Brewster , who `` looks like Karloff , '' on the Broadway stage , but he was unable to do the movie as well because he was still appearing in the play during filming , and Raymond Massey took his place . Hull and Adair , as well as John Alexander ( who played Teddy Brewster ) , were reprising their roles from the 1941 stage production . William Henry Pratt ( 23 November 1887 -- 2 February 1969 ) , better known by his stage name Boris Karloff , was an English actor who was primarily known for his typecast roles in horror films that depicted the characters Frankenstein and The Mummy .
Hypothesis: Arsenic and Old Lace only has female actresses.
