Once Upon a Halloween

Once Upon a Halloween is a 2005 British animated fantasy film featuring the Evil Queen (from Snow White and the Seven Dwarfs) and Disney Villains. The film is an anthology that features clips from Disney animated films plus shorts and songs. While the scenes shown as flashbacks are from traditional animated films, the original scenes of the film featuring the Evil Queen with her cauldron were animated in CGI.

Plot
On the night before Halloween, the Evil Queen from Snow White and the Seven Dwarfs plans to conquer Halloween, and asks her cauldron to show several villains, to which one of them helps her in her plan, such as Peg Leg Pete from Mickey & Friends (in his role as Tiny Tom in Officer Duck), Ursula from The Little Mermaid, Captain Hook from Peter Pan, Yzma from The Emperor's New Groove, Professor Ratigan from The Great Mouse Detective, Alameda Slim from Home on the Range, and Judge Frollo from The Hunchback of Notre Dame. The cauldron also explains its origins and the Horned King, both from The Black Cauldron. At the end however, the cauldron makes the Evil Queen disappear, foiling her plan to take over Halloween.
