 It originally aired on 22 December 2000.
The BAFTA Award for Best Film is given annually by the British Academy of Film and Television Arts and presented at the British Academy Film Awards.
 It has been given since the 1st BAFTA Awards, representing the best films of 1947, but until 1969 it was called the BAFTA Award for Best Film From Any Source.
 It is possible for films from any country to be nominated, although British films are also recognised in the category BAFTA Award for Best British Film and (since 1983) foreign-language films in BAFTA Award for Best Film Not in the English Language.
 As such, there have been multiple occasions of a film being nominated in two of these categories.
The fourth series of British sitcom "Absolutely Fabulous" premiered on BBC One on 31 August 2001.
 The series consisted of six episodes and concluded on 5 October 2001.
 Initially, "Absolutely Fabulous" was to end with the third series, then the final episodes, titled 'The Last Shout', consisting of two specials were created to serve as an official finale to the series.
 However, in 2000, Jennifer Saunders had created and written a television pilot for a proposed upcoming new series, "Mirrorball" in which she intended to reunite the cast of "Ab Fab" in new character roles and a different plot.
 Saunders, along with Joanna Lumley, Julia Sawalha, Jane Horrocks and June Whitfield returned for the pilot.
 A series was never produced.
 However, having the cast reunited for "Mirrorball" inspired Saunders to revive "Ab Fab" and a fourth series was produced.
 A Christmas special, 'Gay' (titled 'Absolutely Fabulous in New York' in the United States) was produced following the fourth series and was broadcast in 2002.
