Michael Winner performed five duties on this movie. Winner was the director, a producer, a co-screenwriter, and billed as Arnold Crust, an editor, and credited as Arnold Crust, Jr., a casting director.
The names of productions displayed on theatre posters in the office of stage director Dafydd Ap Llewellyn (Sir Anthony Hopkins) included "Gigi", "Annie", "My Fair Lady", Guys & Dolls", "The King and I", and "The Wizard of Oz".
Anthony Hopkins wore down the coat he had to wear in the film by jumping on it, scraping it and pouring ink on it and somewhat demolishing it to express through small details his character's insecurities.
According to director Michael Winner, Anthony Hopkins wasn't happy about shooting in the town of Scarborough until he had found out where the Alcoholics Anonymous center was.
