This list charts the most successful films at cinemas in the United Kingdom by box office sales, in pounds sterling and admissions. An overview of the top-earning films and record-holders is provided, as well as the highest-grossing British productions, the most successful non-English language films and the sound films that have generated the most admissions. A summary of the most popular films over the course of the last century is also included.
American productions dominate, with all films earning over £50 million at the box office either completely or partly produced by Hollywood studios. British film is well represented, with about half the films on the list qualifying as British productions; however, due to the globalization of the film industry most successful British productions since the start of the twenty-first century have been co-produced with other countries. There is no universally accepted definition of a film's nationality, so the criteria used by the sources supplying the data are applied where it is given.
The 2015 Star Wars film, The Force Awakens, is the highest-grossing film in terms of nominal box-office sales. The effects of inflation are a significant contributing factor to recent films surpassing the box-office records of older films, so when considering the number of admissions Gone with the Wind (1940) is the most successful film, although this was achieved over several release cycles prior to the home video era.
The highest earners at the box-office are mostly American films and UK-US co-productions. Film series dominate—accounting for twenty-two of the twenty-seven films that have earned in excess of £50 million—including six films in the Harry Potter franchise, Peter Jackson's first four Tolkien adaptations, the four Daniel Craig James Bond films and three Star Wars instalments. Sixteen entries are British co-productions and a further four are based on stories and characters created by British writers. This table only charts films released since 1989, but due to inflation it is unlikely anything released prior to then will surpass the films on the list in nominal terms.
