One of Blair's earliest experiences working in film was in a scene with Paul McCartney in the 1964 film "A Hard Day's Night". McCartney offered to drive Blair home after the shoot, but upon exiting the building, the two were swarmed by fans who scratched and kicked Blair in an attempt to reach McCartney. The following day, she declined a second offer of a ride from McCartney. The scene they had been filming, which was Blair's only scene in the movie, was eventually cut and lost.
