Never Let Me Go is a 2010 British dystopian romantic tragedy film based on Kazuo Ishiguro's 2005 novel Never Let Me Go. The film was directed by Mark Romanek from a screenplay by Alex Garland. Never Let Me Go is set in an alternative history and centres on Kathy, Ruth and Tommy portrayed by Carey Mulligan, Keira Knightley and Andrew Garfield respectively, who become entangled in a love triangle. Principal photography began in April 2009 and lasted several weeks. The movie was filmed at various locations, including Andrew Melville Hall. The film was produced by DNA Films and Film4 on a US$15 million budget.
Prior to the book's publication, Garland had approached the film's producers—Andrew Macdonald and Andrew Reich—about a possible film, and wrote a 96-page script. The producers initially had trouble finding an actress to play Kathy. Mulligan was cast in the role after Peter Rice, the head of the company financing the film, recommended her by text message while watching her performance in An Education. Mulligan, a fan of the book, enthusiastically accepted the role, as it had long been a wish of hers to have the opportunity to play the part. The film's message and themes were the factors that attracted Garfield to become a part of the film.
Never Let Me Go premiered at the 37th annual Telluride Film Festival in September 2010, where the audience responded positively to its message. The film was also screened at festivals including the 2010 Toronto International Film Festival, and the 54th London Film Festival which it opened. The film was distributed by Fox Searchlight Pictures to cinemas in the United States on 15 September 2010, where it was given a limited release. It opened on 14 January 2011 in the United Kingdom. In the United States, Never Let Me Go opened at four theatres, grossing over US$111,000 during its first weekend. The movie got off to a better start in its first weekend in the UK, earning £625,000 and taking ninth place at the box office.
Never Let Me Go earned US$9.5 million at the box office and an additional US$1.89 million in DVD sales revenue. Never Let Me Go was met with generally positive reviews from film critics, with most reviewers praising the cast's performances.
