Frankenweenie

Victor raises Sparky onto the roof with a swing set he attached to the attic skylight.

When he let the kites go on his roof in the same scene, the swing set is gone.

Toward the end of the film, when Sparky has been hooked up to all of the jumper cables, Victor places two cables to Sparky's neck bolts.

When the charge seemingly doesn't take, Victor removes one cable, not two.

When Sparky reawakens and stands up, the second cable is not attached.

When Elsa sings for Dutch Day, the candles on her hat are half melted.

In the next shot, the candles have only melted a tiny bit.

On the chalkboard the word "Life" above the drawing of Sparky disappears in a following scene.

While the Frankenstein family is having fondue, the fondue sticks appear and disappear from the pot.
