Bunny Lake Is Missing

Ann Lake has recently arrived in London from the United States with her four-year-old daughter, Bunny, and her brother Steven, a journalist. On the child's first day at a new school, Ann goes to collect her at the end of the day, but Bunny is not there, and no one at the school seems to remember having seen her. Ann turns to the police, and Superintendent Newhouse takes charge of the investigation. As he and his colleagues look into the matter, the search turns up no record of the girl, and the people questioned cannot confirm that she exists. Doubt begins to settle on whether Bunny is real or a product of Ann's imagination, leaving her to insist on her daughter's existence while the inquiry points elsewhere.

The film is a mystery thriller directed by Otto Preminger, the fifteenth of the sixteen features he made, following In Harm's Way and preceding Rosebud. John Mortimer and Penelope Mortimer wrote the screenplay, and Preminger produced with Martin C. Schute for Columbia Pictures and Wheel Productions. Laurence Olivier plays Newhouse, with Carol Lynley as Ann, Keir Dullea as Steven, and supporting turns from Martita Hunt, Anna Massey and Clive Revill among a credited cast of thirty-eight.

On IMDb the film holds 7.3 out of 10 from around eleven thousand votes, with a 7.2 on TMDB and a critics' rating of 7.2 from fourteen reviews, indicating a steady regard across critics and audiences alike.
