Appeared in the Culture Club video "Do You Really Want To Hurt Me?" in the 1950s health spa sequence.
Her former real-life partner, Douglas Hodge, played her on-screen son, Damian Trotter, in one of the Christmas special episodes of Only Fools and Horses in 1996.
During the episode of Only Fools and Horses (1981) when Raquel gives birth to Damien, Peake-Jones's dialogue was taken from the show's creator John Sullivan's wife when she was in labor. Neither Peake-Jones nor David Jason were parents at that time, so to make the scene realistic, they took advice from midwives at the West Middlesex Hospital while filming the scene.
Her favourite actors and actresses are David Tennant and Judi Dench.
Hobbies include gardening, reading, science and cooking.
