Mr. Belvedere Rings the Bell

Mr. Belvedere Rings the Bell is a 1951 comedy film, the third and final one starring Clifton Webb as Lynn Belvedere. It follows on from Sitting Pretty 1948 and Mr. Belvedere Goes to College 1949.

The film was based on the play The Silver Whistle by Robert E. MacEnroe. Although the plot of the film resembles that of the play, Belvedere was not a character in the play. The leading character was a hobo named Oliver Erwenter, played by Jos Ferrer. The Silver Whistle, with all of its original characters, was telecast in 1959 on Playhouse 90, in which Eddie Albert played the role of Erwenter.
