If Tim Burton's 'Frankenweenie' is about the ghoulish things that children love, those kids may be surprised that the film features something that's actually terrifying: Substitute teachers. In this new clip from the film, we see Martin Landau's Mr. Ryzkruski talk about lightning.

Adapted from Tim Burton's 1984 short film of the same name (and the short that launched his career), we're hoping that going back to his roots re-energizes the director after his last couple films, which have mostly been terrible. Fingers crossed. Here's the synopsis:

From creative genius Tim Burton (“Alice in Wonderland,” The Nightmare Before Christmas”) comes “Frankenweenie,” a heartwarming tale about a boy and his dog. After unexpectedly losing his beloved dog Sparky, young Victor harnesses the power of science to bring his best friend back to life—with just a few minor adjustments. He tries to hide his home-sewn creation, but when Sparky gets out, Victor’s fellow students, teachers and the entire town all learn that getting a new “leash on life” can be monstrous.

A stop-motion animated film, “Frankenweenie” will be filmed in black and white and rendered in 3D, which will elevate the classic style to a whole new experience.

In Tim Burton’s “Frankenweenie” young Victor conducts a science experiment to bring his beloved dog Sparky back to life, only to face unintended, sometimes monstrous, consequences.
