Prather first began acting in grade-school stage productions, and was a regular on the teen dance show "Sump'n Else" during her high school years.
[citation needed] Her film credits include The Single Girls (1974), Big Bad Mama (1974), The Devil's Rain (1975), Smile (1975), Rabbit Test (1978) and Take This Job and Shove It (1981).
She appeared in TV series such as Executive Suite, Eight Is Enough, CHiPs, Fantasy Island, and the 1980 edition of Battle of the Network Stars.
The show ran from 1965 to 1968 and it was roughly modeled after "American Bandstand" and often featured national and local bands.
[citation needed] While on the set of The Devil's Rain, Prather told an "extremely unhappy" John Travolta that Scientology had helped her, inspiring him to get involved with the religion upon his later return to Los Angeles.
