I wanted to do art. Art was my love. I went to art school in Brighton but I was not very good at it. I just did not know what to do. I had a friend at the college who was studying photography and he needed somebody to photograph and he asked me. Unbeknownst to me, he sent the photographs to a big newspaper in London. The fashion photographer, David Bailey, was conducting a photo contest and my picture won.
Munro's career commenced in 1966 when her mother and a Photographer friend entered some headshots of her in The Evening News's "Face of the Year" contest. As she said:
Munro continued to work in numerous British and European horror and science fiction films through the 1970s and 1980s, most notably Starcrash with David Hasselhoff, Christopher Plummer and Marjoe Gortner.
In 1971 she appeared alongside Vincent Price in The Abominable Dr Phibes, playing the deceased Victoria Regina Phibes. She recalled:
Hammer Films CEO, Sir James Carreras, spotted Munro on a Lamb's Navy Rum poster/billboard. He asked his assistant, James Liggett, to find and screen test her. She was promptly signed to a one-year contract. Her first film for Hammer proved to be a turning point in her career. It was during the making of Dracula AD 1972 that she decided from this film onward she was a full-fledged Actress.
In 1974 Munro acted in Captain Kronos – Vampire Hunter. Directed by Brian Clemens, she played the barefoot gypsy girl Carla. In Paramount Pictures DVD commentary, Clemens explains that he envisioned the role as a fiery, Raquel Welch-type, redhead.
In 1977, Munro turned down the opportunity to play villainess Ursa in Superman in favour of Naomi in The Spy Who Loved Me.
Throughout the 1980s, Munro was reported as being a candidate for the co-starring role in a rumoured, but never produced, feature film based upon Doctor Who. The feature was reported to be co-produced by her second husband George Dugdale.
In 1984, Munro collaborated with Gary Numan for the single "Pump Me Up", which was released on Numan's Numa record label.
Her film roles were confined to performing cameos as herself in Night Owl (1993), as Mrs. Pignon in To Die For (1994), as the counsellor in her friend Jeffrey Arsenault's film Domestic Strangers (1996), and as Carla the Gypsy in Flesh for the Beast (2003).
