Sinatra played a secretary in the 1963 Burke's Law episode "Who Killed Wade Walker." She starred in three beach party films: "For Those Who Think Young" (1964), "Get Yourself a College Girl" (1964) and "The Ghost in the Invisible Bikini" (1966), performing songs in the latter film. After securing the role that eventually went to Linda Evans in "Beach Blanket Bingo", she withdrew because the film's character is kidnapped—a parallel she found too close to actual events when her brother Frank Sinatra Jr. was kidnapped in December 1963.
