"Male ingénue" Theodore Newton was signed to a Warner Bros. contract in 1933, whereupon he spent the next year or so playing nominal romantic leads in films like the George Arliss vehicles The Working Man and Voltaire. Newton was given the chance to toughen up his callow screen image when he was loaned out to Monogram to play a fast-talking crime reporter in The Sphinx (1933), which remains his most memorable film performance. After playing a handful of secondary roles for RKO, he left Hollywood in 1935 to concentrate on stage work. Theodore Newton returned to the screen as a character actor in 1945, playing various authority figures (usually military officers) until his retirement in 1959. ~ Hal Erickson, All Movie Guide
