The Last September is a 1999 British drama film directed by Deborah Warner and produced by Yvonne Thunder from a screenplay by John Banville.

The film stars an ensemble cast, which includes Maggie Smith, Michael Gambon, Keeley Hawes, David Tennant and Lambert Wilson.

Set in the early 1920s, Anglo-Irish landowners Sir Richard and Lady Myra Naylor reside in their country estate with their high-spirited niece, Lois, and their nephew Laurence during the twilight of British rule in southern Ireland.

The arrival of Marda Norton causes an upheaval amongst all in the house as does an escaped commander of the Irish Volunteers who is on the run from local British soldiers and police.

She plunges into the forest with a hand-held camera and shoots her characters through windows, door frames and even the wrong end of a telescope in a heroic effort to trouble the placid surface of their lives, and to make her film resemble something other than an episode of Masterpiece Theater.
