Ron Cook is an English actor best known for his starring role as Mr. Crabb, Selfridges' chief accountant who is concerned more often than not by Harry's finances, spontaneous decisions and judgment, in the period drama television series Mr Selfridge.
Cook grew up in Coventry, England, where he had a "vague idea of being a teacher." It was his headmaster who told him he came alive on stage, so Cook decided to study theatre in education.
He got his first job as the front half of a horse in a stage production of Aladdin and has been acting ever since.
Professionally acting since the mid-1970s, Cook has had a prolific career in theatre, film, and television. His list of screen credits includes the films Chocolat, Hot Fuzz, Topsy Turvy, and Quills; and the Masterpiece productions The Mystery of Edwin Drood, The Diary of Anne Frank, The Hound of the Baskervilles, The Lost Prince, Casanova, He Knew He Was Right, Filth and Little Dorrit.
Cook has also appeared in the stage productions of Twelfth Night, alongside Derek Jacobi, The Seafarer, and Juno and the Paycock, which earned him a Laurence Olivier Award (England's most prestigious theater award) in 2000.
