It was an early work in the Michelle Pfeiffer's career, Lux Soap Commercial.

It is dated after the filming of Falling In Love Again (1979), her first film. So it should be 1979/80: according the script of the advertisement published on magazines: 'She's has just finished work on Falling In Love Again for actor-turned-director Steven Paul'
