The ad series led to numerous film and television offers and a three-page profile in TV Guide (August 20-26, 1966). By 1968, Dodge executives felt Austin's popularity was overshadowing the cars and began a new "Dodge Fever" campaign with a different model, Joan Anita Parker.
In August 1967 she starred in the adventure-comedy film The Perils of Pauline based on the silent cliff-hanger serial. Posters for the film referenced her Dodge commercials: That "Rebellion Girl" is dodgin' unbelievable perils...
In 1968 she was a semi-regular on the hit comedy series Rowan & Martin's Laugh-In during its first season. Austin performed in various comedy sketches, song-and-dance numbers, and pre-filmed segments, including an early music video for "Buy For Me The Rain" by The Nitty Gritty Dirt Band.
