In 2019, she was inducted into the Rondo Hatton Classic Horror Awards' Monster Kid Hall of Fame.

She engaged in a "catfight" scene with her rival Vida (played by former Miss Israel Aliza Gur).

She then appeared in various Hammer Studio low-budget films, most notably Prehistoric Women (1967) (aka Slave Girls of the White Rhinoceros) and the gender-bending horror Dr. Jekyll and Sister Hyde (1971), in which she played the titular villainess.

She made numerous guest appearances on television series, including Sledge Hammer!, Fantasy Island, The Fall Guy, Mannix, The Six Million Dollar Man and Falcon Crest.

She owned a removals business in London, but is now semiretired except for her guest appearances at international Bond conventions.

After a 24 year absence from the screen, Beswick came out of retirement in 2018 to appear in House of the Gorgon opposite fellow Hammer film actors Caroline Munro, Veronica Carlson, and Christopher Neame.
