The game takes place in a cinema or something movie related, where you get access to some of the most critically acclaimed movies of all time.

And the main villain/horror monster is an animatronic of Roger Ebert.

The animatronic has a weird open mouth, because it's based on when he had his jaw removed.

And when he catches you, he opens his weird mouth and reveals rows of sharp metallic teeth and eats you.

Maybe the game revolves around going to some theaters and you "watch" the movies as if you're getting inside them as if there's levels based off made up movies in the game's universe.

Also, there's a creepypasta about a game called The Theater.

Actually, the whole reason for this post is because of the idea of making a horror monster out of jawless Roger Ebert, like how there's an urban legend about the Ayuwoki MIchael Jackson animatronic.
