Very old 'teenagers'!

Rating: 6/10 (16 July 2017)

This is a romantic comedy musical film that was released in 1978, but is set in 1958 in Los Angeles.
The film is well-written and well-acted, with good song-and-dance routines. Its main fault is that many of the high school pupils are played by people who were well into their twenties or even their thirties and don't pass for the 17 or 18-year-olds that they're playing.
