Mr. Belvedere Rings the Bell is a 1951 comedy film, the third and final one starring Clifton Webb as Lynn Belvedere. Mr. Belvedere lies about his age to gain entrance to a senior citizens home, where he tries to determine if there is any value in growing old. He inspires the residents of the facility, and teaches them that life is worth living if you use your imagination.
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 José 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.
