Due to her connection to Roger Moore, she has twice made appearances in James Bond-related productions. She played a secretary in the 1989 biopic Goldeneye: The Secret Life of Ian Fleming and later made a cameo appearance as a flight attendant in the 2002 Bond film, Die Another Day. Her godfather was the late actor Robert Brown, her father's co-star in the television series Ivanhoe and 3 Bond films.
In 2006, Moore made the film Provoked. Jagmohan Mundhra's film is based on the landmark UKdomestic violence case in which Kiranjit Singh Ahluwalia was jailed in London for killing her abusive husband. Based on her story, the film stars Aishwarya Rai as Ahluwalia. Moore plays Jackie, another prison inmate.
Moore appears as Alfidia, the mother of a fictionalised Livia, in two 2007 episodes of the HBO/BBC series Rome. In A Necessary Fiction, she is present when a married Livia catches the eye of young Octavian, and both women are pleased when he insists that Livia divorce her current husband to marry him. Later, in De Patre Vostro, Alfidia lightly questions Octavia's loyalty to her family at dinner, and is present when Atia of the Julii finally puts daughter-in-law Livia in her place.
