After beginning her career in her native England, Collins came to Hollywood in the 1955. She mostly appeared in minor movies and made guest appearances on TV shows before joining "Dynasty." Her performance on the show is generally credited with making it into the ratings success it became, topping the ratings in 1985 to beat out its chief competitor "Dallas." Collins has continued working consistently since "Dynasty," making guest appearances on shows such as "Roseanne," "The Nanny" and "Will & Grace" and appearing in the occasional movie, including playing Wilma Flintstone's mother in the 2000 prequel "The Flintstones in Viva Rock Vegas." Her most recent roles have come in the form of guest spots in the sitcoms "Rules of Engagement" and "Happily Divorced" and in the British TV series "Benidorm" and a recurring role on the E! drama series "The Royals."
