Seagulls Over Sorrento, released as Crest of the Wave in the United States, is a 1954 British drama film made by the Boulting Brothers based on the play of the same name by Hugh Hastings. The film stars Gene Kelly and was one of three made by Kelly in Europe over an 18month period to make use of frozen MGM funds. The cast features John Justin, Bernard Lee and Jeff Richards. Although the film finished shooting in July 1953, MGM could not release it in the UK until the play finished its London run, which delayed the films release for almost a year.
The original stage play was written by Australian playwright Hugh Hastings and was based on his experiences in World War II. It opened in Londons West End onJune 1950, and was a hit there, but played for only two weeks on Broadway in New York City.The play ran for over 1,600 performances in London. Film rights were sold to the Boulting Brothers for 10,000. ........
