Which alternative animated film was directed by Henry Selick and produced by Tim Burton?

The alternative animated film directed by Henry Selick and produced by Tim Burton is The Nightmare Before Christmas. It was released in 1993 and uses stop-motion animation.

The story follows Jack Skellington, the Pumpkin King of Halloween Town, who discovers Christmas Town and attempts to organize Christmas himself. Chris Sarandon provides Jack's speaking voice, while Danny Elfman sings Jack's songs and composed the score. Catherine O'Hara voices Sally.

The film was based on a poem and concept by Tim Burton, who was working on Batman Returns when production began. It was distributed by Walt Disney Pictures under the Touchstone Pictures label because Disney considered its tone unusually dark for its traditional animated audience. The film later became a widely recognized holiday classic.
