Project 2 film ideas

I will be doing a short film based on a 17 year old boy who still believes in Santa Claus. It will be a mockumentary with interviews of his fake mum, dad and other family and friends. Since his parents got divorced and he lives only with his mum he uses Santa as a father figure. His room will be covered in Christmas decorations all year round; there will be photo frames filled with pictures the boy has of him and Santa (photoshopped). He even changed his last name to Claus.
