I'm trying to find the name of an OLD film. My sister said it may be called the Devil's spawn which I have not been able to find.
What I remember about the film is that it was in black and white. The boy was young around ten years old and he was possessed. The mother tried to take care of him but couldn't. She called someone for an exorcism. In the end the house starts to burn down and the mother leaves leaving the child in the house to burn down with it. I specifically remember it was a green demon that escaped the boy.
Again it is really old because the effects were terrible. I watched it when I was about 4 years old and even then it was an old film. I ask for the year because there are so many it's hard to find it based on the name.
