In Search of New Ideas

Although I have found a decent story, I am still not completely certain that it is the film choice for me. That is why I am going to and search for other ideas through research and finding inspiration from other short films on the internet. To narrow my search down, I am wanting to look for a thriller/ horror idea; a Stephen King short story may be a good place to start looking. I also want to have the story centred around a child or teenager as I have better access to actors and actresses around this age.
