Comission from

So Charon seemed to be into creating the ultimate crossover picture, so he asked for Jack Skellington riding a Graboid while V from V for Vendetta explains to Tron how he has to rise against his user and kill him. In the midst of all this is poor Movie Slate, wondering who casted the "come to life" spell in her movie collection to bring all these characters to life. I don't have a logical explanation for it. If you want to come up with your own and have a starting point, consider how Twilight has been practicing her magic spells a lot more recently. Who knows if one of those spells ricochetted and hit Slate's cinema?
I don't know, really. Oh, and her cinema's name is "The Lumiere". I found it fitting.
