In the wonderful John Sayles film The Secret of Roan Inish (1994), the director presents a touching tale of a family with selkie connections.
The film was based on the the novel Secret of the Ron Mor Skerry, by Rosalie K. Fry.
(Although the novel takes place in Scotland, while the film is set in Ireland, the location change wouldn't have presented a problem for the selkies, per the excellent swimming abilities;)
I know the film and book to be based on folktales in general, but are there specific stories from which it derives?
