Movies like The Pirates of Penzance

This movie is an adaptation of Gilbert and Sullivan's comic operetta of the same name, with parts of other of their operettas stirred in. Frederic (Rex Smith) has fallen in love with sweet innocent Mabel Stanley (Linda Ronstadt). Yet his vocation is an impediment to their union. Perhaps the situation can be rectified by his old nurse, Ruth (Dame Angela Lansbury), who made a dreadful blunder years before. A highlight is the song and dance, "A Policeman's Lot is Not a Happy One".
