Turtle Diary (1985)

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 of each other, both perceive 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, which they ultimately succeed in accomplishing. Their release of the turtles represents metaphorically their release of themselves from their own inhibitions.
