Ring of Bright Water is a 1969 British comedy-drama film directed by Jack Couffer and starring Bill Travers and Virginia McKenna.

The otter wreaks havoc in his small flat, and together they leave London for a rustic cottage overlooking the sea on the west coast of Scotland.

Mij's inquisitive and adventurous nature leads him some distance from the cottage to a female otter with whom he spends the day.

The film held its premiere in aid of the World Wildlife Fund on 2 April 1969 at the Odeon Leicester Square attended by the Prince Philip, Duke of Edinburgh.

[2] The Monthly Film Bulletin wrote: "Routine cuddly animal stuff, eminently suitable for family audiences to bill and coo over, and about which there is absolutely nothing to be said except that the otters are appealing, the photography is passable, and the almost non-existent story padded out interminably with cute incident.

"[7] Variety called the film "engaging" and noted "Travers and McKenna unselfishly subdue their performances to the star demands of the lolloping young rascal, Mij, but keep the interest firmly alive by their tactful playing.

[11] The documentary film Echoes of Camusfearna (1995) contains previously unseen footage of Gavin Maxwell with the otters, and is introduced and narrated by Virginia McKenna.
