In addition to his longstanding association with Hitchcock, Williams appeared in three Billy Wilder films over the course of his career: "Sabrina" (1954), "Witness for the Prosecution" (1957), and "The Private Life of Sherlock Holmes" (1970). In "Holmes", however, his scenes were among the 60 to 75 minutes cut by the studio prior to the film's release, when the studio decided not to release it in its intended roadshow format. Williams' scenes, along with the majority of the cut material, have not been recovered.
