Uncredited final theatrical feature film of John Drew Barrymore. After finishing this film he left the industry and became a recluse for the next 25 years.
This movie was made and first released about five years after the similarly themed youth wartime romance film "Un été 42 (1971)", which had been successful at the box office. This movie is set in 1943, which is about one year after the 'Summer of '42'.
Reportedly, star Jan-Michael Vincent, who played Marion Hedgepeth, performed his own water stunts at the McCloud River in northern California, USA.
Screenwriter Stanford Whitmore derived the film's story from his own personal experience as a seventeen-year-old Marine enlisted in San Diego in California, USA according to an article published in the summer 1976 edition of the publication 'Liberty'.
The film's screenplay by Stanford Whitmore was announced as being acquired by Spelling-Goldberg Productions in an article published in the 12th February 1975 of show-business trade-paper 'The Hollywood Reporter'.
