This is the only Alfred Hitchcock movie to carry an "18" certificate in the U.K., or receive an "X" rating after the "X" age restriction was moved from sixteen to eighteen in 1971.
Alfred Hitchcock's shooting schedule allowed filming to begin at 8 a.m. and finish at 6 p.m. every day while on-location in Covent Garden in London. One day during filming, Hitchcock was in the middle of finishing a take when a union representative showed up to inform him that it was 6:15 p.m., and that they had to stop filming. Hitchcock became furious and threatened to walk off the set, and film this movie back in Hollywood. After that, no more union representatives were allowed on the set.
The role of Robert Rusk was originally offered to Michael Caine. He thought the character was disgusting, and said "I don't want to be associated with the part." After Caine declined the role, he later mentioned in his memoirs how Alfred Hitchcock completely ignored him when they met in a hotel a few years later.
