Turtle Diary

Two lonely Londoners, Neaera Duncan, a children's author (Glenda Jackson), and William Snow, a bookstore assistant (Ben Kingsley), find common ground when visiting the sea turtles at London Zoo. Independently, each perceives that the turtles are unnaturally confined, and they hatch a plan with the assistance of zookeeper George Fairbairn (Michael Gambon) to smuggle them out and release them into the sea.

Their release of the turtles is a metaphor for their escape from their inhibitions.

• Glenda Jackson as Neaera Duncan, a "Popular children's author … fearing her creative talents have evaporated, [who] escapes into the dreamy world of sea turtles seeking inspiration in their beauty and grace."
• Ben Kingsley as William Snow, "a humble assistant in a bookstore where he, too, dreams of the turtles."
• Richard Johnson as Mr. Johnson, a neighbor of Neaera Duncan
• Michael Gambon as George Fairbairn, the zookeeper charged with caring for the turtles
• Jeroen Krabbé as Mr. Sandor, a neighbor of William Snow
• Rosemary Leach as Mrs. Charlie Inchcliff, Williams Snow's landlady
• Eleanor Bron as Miss Neap, a neighbor of William Snow
• Harriet Walter as Harriet Simms, a colleague of William Snow at the bookstore
• Nigel Hawthorne as the publisher of books by Neaera Duncan

Harold Pinter has a cameo role as a man in the bookshop where William and Harriet work.

The film was made by United British Artists.

In his 1985 review of the film for The Sunday Telegraph, David Castell observes that Pinter's screenplay concentrates on developing dialogue and plot, leaving clues for the actors to convey their characters' subtle emotional and psychological development: "It is hard to think of two actors better matched to play Pinter than Glenda Jackson and Ben Kingsley. They milk every nuance, point up every missed beat and relish each irony and repetition in the script. … Turtle Diary is a fine film that charts movingly the unnoticed despair of everyday lives, the sufferings of those who endure loneliness in silence."

The film grossed $2.2 million on its American theatrical release. It was one of the most successful films from United British Artists.

The film was released on videocassette in 1985 by Vestron Video. The film has not been released on DVD.
