According the Internet Movie Database, as of 2010, Walt Disney Pictures has made more than 400 films. Walt Disney Productions has made more than 1000 films. Walt Disney himself won 22 Oscars personally. The following is necessarily a partial list.
Depending on your definition of the genre "Fantasy," the main winner of Oscars{R} would have to be _Lord of the Rings - Return of the King_. The two previous parts of this trilogy were nominated for Best Picture, but did not win.
Ditto for _Wizard of Oz_ and _A Midsummer's Night Dream_.
Films that SOME would consider fantasy that were nominated include _Field of Dreams_, as well as both versions of _Heaven Can Wait_.
The Lord of the Rings: The Return of the King (2003) was the first and only fantasy film to win an Oscar for Best Picture.
While the best is subjective, many people believe the best fantasy film was The Wizard of Oz. It has had decades to take hold and will forever remain a classic film.
