Caravans is a 1978 IranianAmerican film directed by James Fargo based on the novel by James A. Michener. Nancy Voyles Crawford wrote the screenplay. The movie was shot in Iran and starred Anthony Quinn, Jennifer ONeill, and Michael Sarrazin.
The film was not well received by James Michener as it strayed wildly from the plot of his book, even eradicating its main character, a Nazi war criminal on the run who falls in love with the female lead character. This omission and other story changes caused Michener to take legal action.Mike Batt wrote the score, which has been the most successful element of the film, remaining a bestseller for many years after the films release. The song Caravan Song was written by Mike Batt and sung by the Scottish singer Barbara Dickson. It peaked at No. 41 in UK charts and featured on the album All for a Song. ........
