Never Let Me Go is a 2010 British dystopian romantic tragedy film based on Kazuo Ishiguro's 2005 novel of the same name. 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. Filming locations included Andrew Melville Hall and Forest School, Walthamstow. The film was produced by DNA Films and Film4 on a US$15 million budget.

Prior to the book's publication, Garland had approached Andrew Macdonald and Allon 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 she had long desired to play the part. The film's message and themes were the factors that attracted Garfield to 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 the 2011 Toronto International Film Festival, and it opened the 53rd London Film Festival. 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 its portrayals.
