That Girl is an American sitcom that ran on ABC from 1966 to 1971. It stars Marlo Thomas as the title character Ann Marie, an aspiring actress, who moves from her hometown of Brewster, New York to try to make it big in New York City. Ann has to take a number of offbeat "temp" jobs to support herself in between her various auditions and bit parts. Ted Bessell played her boyfriend Donald Hollinger, a writer for Newsview Magazine; Lew Parker and Rosemary DeCamp played Lew Marie and Helen Marie, her concerned parents. Bernie Kopell, Ruth Buzzi and Reva Rose played Ann and Donald's friends. That Girl was developed by writers Bill Persky and Sam Denoff, who had served as head writers on The Dick Van Dyke Show earlier in the 1960s.

Quiet, withdrawn 13-year-old Rynn Jacobs lives peacefully in her home in a New England beach town. Whenever the prying landlady inquires after Rynn's father, she politely claims that he's in the city on business. But when the landlady's creepy and increasingly persistent son, Frank, won't leave Rynn alone, she teams up with kindly neighbor boy Mario to maintain the dark family secret that she's been keeping to herself.
