Kate Winslet in the context of "Eternal Sunshine of the Spotless Mind"

British cinema has significantly influenced the global film industry since the 19th century. The oldest known surviving film in the world, Roundhay Garden Scene (1888), was shot in England by French inventor Louis Le Prince. Early colour films were also pioneered in the UK. Film production reached an all-time high in 1936, but the "golden age" of British cinema is usually thought to have occurred in the 1940s, which saw the release of the most critically acclaimed works by filmmakers such as David Lean, Michael Powell, and Carol Reed.

Many British actors have accrued critical success and worldwide recognition, including Alec Guinness, Patrick Stewart, Julie Andrews, Michael Caine, Joan Collins, Sean Connery, Olivia Colman, Benedict Cumberbatch, Daniel Craig, Daniel Day-Lewis, Judi Dench, Helen Mirren, Olivia de Havilland, Audrey Hepburn, Anthony Hopkins, Glynis Johns, Vivien Leigh, Ian Mckellen, Peter O'Toole, Gary Oldman, Laurence Olivier, John Gielgud, Maggie Smith, Joan Plowright, Emma Thompson, Rachel Weisz, Kate Winslet and Keira Knightley. Some of the films with the largest ever box office profits have been made in the United Kingdom, including Harry Potter and James Bond, the fourth and fifth highest-grossing film franchises of all time.

Finding Neverland is a 2004 biographical fantasy film directed by Marc Forster and written by David Magee, based on the 1998 play The Man Who Was Peter Pan by Allan Knee. The film stars Johnny Depp, Kate Winslet, Julie Christie, Radha Mitchell, and Dustin Hoffman, with Freddie Highmore in a supporting role.

Finding Neverland premiered at the Venice Film Festival on September 4, 2004, and was released in the United Kingdom on October 29, 2004, and the United States on December 17, 2004 by Miramax Films. It was a box office success, grossing $116.8 million worldwide. The film earned seven nominations at the 77th Academy Awards, including Best Picture, Best Adapted Screenplay, and Best Actor for Depp, and won for Best Original Score. The film was the inspiration for the stage musical of the same name in 2012.

Revolutionary Road is a 2008 romantic drama film directed by Sam Mendes and written by Justin Haythe, based on the 1961 novel of the same name by Richard Yates. It stars Leonardo DiCaprio and Kate Winslet as Frank and April Wheeler, with Michael Shannon, Kathryn Hahn, David Harbour, and Kathy Bates in supporting roles. Set from the late 1940s to the mid-1950s, the film portrays the Wheelers' struggle to cope with their personal problems and the ensuing breakdown in their marriage. Revolutionary Road is the second onscreen collaboration for DiCaprio, Winslet, and Bates, all of whom previously co-starred in 1997's Titanic. The film soundtrack was composed by Thomas Newman, his fourth collaboration with Mendes.

Development of the film adaptation began in 1961. However, a lack of commercial prospects and disagreements with the screenplay caused the project to be in limbo until the 2000s. BBC Films eventually purchased the film rights to the novel and Haythe rewrote the screenplay. Winslet read the script and persuaded her then-husband Mendes to direct, and DiCaprio to play the role of Frank.
