Heather Menzies made her film debut at 15, as Louisa von Trapp in The Sound of Music (1965). Menzies followed this assignment with several well-scrubbed ingenue roles; she was prominently featured in one of the deathless anti-drug Dragnet episodes of the late 1960s. She underwent a startling image change in the 1970s, playing sexy roles with a minimum of clothing. In the 1977 TV-series version of Logan's Run, she was cast as Jessica 6, accruing a great deal of press attention for her extremely revealing costumes. She apparently retired after 1982's Endangered Species. Heather Menzies was married to actor Robert Urich. ~ Hal Erickson, All Movie Guide
