She was only in one film and had another acting credit for an episode of a tv show but the film was GOLDFINGER, one of the biggest motion pictures of the 1960s. In the film Tania Mallet played Tilly Masterson, a gorgeous blonde who is out to avenge the murder of her sister Jill (Shirley Eaton) that had been ordered by the title character. Mallet who was already a well established, very well paid fashion model didn't care for the long hours involved in making movies, nor all of the time waiting around for the next shot. She decided to remain in modelling which she did until the early 1970s.
