Dakota Johnson, Henry Golding, and Cosmo Jarvis Lead Netflix's "Persuasion"

Smith, who also goes by the stage name Doc Brown, is an English rapper, comedian, and actor who can most recently be seen as Richie Hansen on "The Split." Although we still don't know what role he'll be playing, his comedic roots suggest he might play Charles Musgrove, Mary's cheerful husband, or Admiral Croft, Captain Wentworth's good-natured brother-in-law.
