Somewhere in Time is a 1980 American romantic fantasy drama film directed by Jeannot Szwarc. It is a film adaptation of the 1975 novel Bid Time Return by Richard Matheson, who also wrote the screenplay. The film stars Christopher Reeve, Jane Seymour, and Christopher Plummer.

The original musical score for the film was composed and conducted by John Barry, who was suggested by Jane Seymour, a personal friend of his. Until then the producers were thinking of having a score based on The 18th variation of Sergei Rachmaninoff's "Rhapsody on a Theme of Paganini" which is used in the film several times. In lieu of a fee, Barry took a percentage of the royalties on the soundtrack, which went on to become his best-selling film score.
