The Return of the King, the last in The Lord of the Rings trilogy, will be released on DVD and video three months sooner than expected.
Peter Jackson's The Return of the King won 11 Oscars
The film, which won 11 Oscars last month, will be released on 25 May, producers New Line said.
Fans had to wait until August 2002 and 2003 for DVD versions of the first two Rings films.
An extended version of the film - including previously unseen footage - will follow at the end of the year.
The initial DVD release of the film will include the film, as well as a 20-minute theatrical trailer and a range of behind-the-scenes material.
The Fellowship of the Ring and The Two Towers were also released with extended versions on DVD.
The extended version of the film - which will be considerably longer than the three hours and 21 minutes in the theatrical version - will make the trio of extended versions more than 11 hours long.
The DVD is expected to be one of the year's biggest releases.
New Zealand director Peter Jackson, who won best director at the Oscars for Return of the King, is soon to begin work on his version of the 1933 adventure King Kong. It is due for release in 2005.
