Pretty, girlish British ingenue who began her career playing plucky nymphets. She made her film debut in 1967 as a schoolgirl in To Sir With Love which she followed up with roles in the prominent British features Prudence and the Pill (1968) and Three Into Two Won't Go (1969). Geeson proved to be an appealing female lead, albeit one of limited ability. Much of her subsequent film work has been in low-rung horror efforts, including Doomwatch (1972) and Horror Planet (1982), the latter a career nadir in which she plays a woman raped by an alien creature. More recently she has been active on stage and television, both in England and the U.S.
