As a child I saw two horrors movies i can no longer name.

The first was a movie about a little girl who drew pictures of a house. This house came to life. In this house lived a killer. The little girl and her older sister were pulled into the house and had to escape.

The second was a movie about a young man (maybe 18 years old) who had an interest in mythological beasts. As fate would have it he had the chance to visit a theme park in which there was a giant robotic dragon exibit for some particular ride. This "dragon" was more than a simply machine. It apparently was "a live". It requested the boy complete him as planned by the designers who had apparently abandoned the project.

Can any of you name these movies?
