There are big differences between horror flicks and books. If you aren't specifically looking or deconstructing the movie, you won't notice.
For starters, pace. Movies use music to set or punctuate a pace. It's a bit of faking that you can't fake in writing. Movies use a lot of jump scares (loud noises, cat jumping into view, etc) can't do that in novels either.

To write effective horror you must:

1. Make the reader care what happens to the characters
2. Make the reader fear what will happen to the characters
3. Create a suspension of disbelief that transports your reader to your world

Then pick what type of horror you want to write, read many books and go.
