I came up with an idea for a web series about 3-4 years ago. I told my friend from film school about the idea, and he said he would join me. We tried writing a script one time but we just ended up failing and watched a movie instead. I've brought it up that I want to try filming it again, and he was up for it. I brought it up to him a couple of months ago, and he said he would be down to try coming up with scripts and ideas again. But now I dont think working with him is a good idea. He likes different kinds of movies, and I dont like most of the movies that he likes. I also think that hes not a perfectionist like I am, and wouldn't be 100% focused on doing the best job as possible. If I were to go on without him and became successful, would he have any case against me if he were to sue me? I came up with the original idea, and no ideas or scripts have been written at all.
