It's a movie about a little boy who goes to an old ladys house she traps him in a jail cell and he has to read her stories about different monster and she's giong to cook him

Tales from the Darkside: The Movie (1990) (http://www.imdb.com/title/tt0100740/)

Tales from the Darkside don't sound right to me it sounds more like a movie called DeadTime Stories.

You're welcome.
