Movie where little boy draws evil man on paper that becomes real and in the end, the little boy puts the paper on the stove to make it catch on fire, killing the evil man.Help

That sounds like one of the short stories from Tales from the Hood (1995) (http://www.imdb.com/title/tt0114609/)

Here's a link so you can watch that portion of the movie http://www.youtube.com/watch?v=AhdpToA-I70

Also sounds a bit like Paperhouse.
