The British Academy Film Awards are presented in an annual award show hosted by the British Academy of Film and Television Arts (BAFTA). It is the British counterpart of the Oscars. As of 2008, it has taken place in the Royal Opera House, having taken over from the flagship Odeon cinema on Leicester Square. The 65th British Academy Film Awards took place on 12 February 2012.

BAFTA was founded in 1947 as The British Film Academy, by David Lean, Alexander Korda, Carol Reed, Charles Laughton, Roger Manvell and others. In 1958, the Academy merged with The Guild of Television Producers and Directors to form The Society of Film and Television, which eventually became The British Academy of Film and Television Arts in 1976.

BAFTA's stated charitable remit is to "support, develop and promote the art forms of the moving image, by identifying and rewarding excellence, inspiring practitioners and benefiting the public". In addition to high profile awards ceremonies BAFTA runs a year-round programme of educational events including film screenings and tribute evenings. BAFTA is supported by a membership of around 6,000 people from the film, television and video game industries.

Heath Andrew Ledger (4 April 1979 – 22 January 2008) was an Australian television and film actor. After performing roles in Australian television and film during the 1990s, Ledger left his homeland for the United States in 1998 to develop his film career. His work comprised nineteen films, including 10 Things I Hate About You (1999), The Patriot (2000), A Knight's Tale (2001), Brokeback Mountain (2005), and The Dark Knight (2008). In addition to acting, he produced and directed music videos and aspired to be a film director.

For his portrayal of Ennis Del Mar in Brokeback Mountain, Ledger won the 2005 New York Film Critics Circle Award for Best Actor and the 2006 "Best Actor" award from the Australian Film Institute and was nominated for the 2005 Academy Award for Best Actor as well as the 2006 BAFTA Award for Best Actor in a Leading Role. Posthumously he shared the 2007 Independent Spirit Robert Altman Award with the rest of the ensemble cast, the director, and the casting director for the film I'm Not There, which was inspired by the life and songs of American singer-songwriter Bob Dylan. In the film, Ledger portrayed a fictional actor named Robbie Clark, one of six characters embodying aspects of Dylan's life and persona. Ledger received numerous accolades for his critically acclaimed portrayal of the Joker in The Dark Knight, including the Academy Award for Best Supporting Actor, a Best Actor International Award at the 2008 Australian Film Institute Awards, for which he became the first actor to win an award posthumously, the 2008 Los Angeles Film Critics Association Award for Best Supporting Actor, the 2009 Golden Globe Award for Best Supporting Actor and the 2009 BAFTA Award for Best Supporting Actor.
