I did not see the movies of the original post, nor the Lion King.
Walter Bishop, definitively. Although he is so extreme I would almost tend to say he is psychotic, maybe schizophrenic. Fox Mulder, yes, I would say so.
What makes me think Neo is based on schizotypal traits is because the savior thing is usually so. The type of self-sacrificing hero is pretty much trait-like. He is a thinker and versed in the programming. He is also thinking outside the box, obviously, and has magic thinking. The power in the matrix comes from magic thinking. Being able to imagine things is more important than anything else. I only saw the first movie though, so it is based only on that. Not everybody that takes the pill is schizotypal. I don't consider the others as such. Not the black guy nor even Trinity. Maybe the Oracle, but the acting is wrong if that is the case. It has to do more about the actor, IMO than the actual character. If the actor is well cast, it creates a better picture. Otherwise, you are looking at stereotypes, which may be badly represented.
Some actors that give a schizotypal feel to their acting are Tom Cruise, Sean Connery, Christophe Lambert, Humphrey Bogart, and many others. Angelina Jolie also, Audrey Hepburn. Michael Keaton, very much so.
Sherlock Holmes is an interesting case. For the most part, he looks more schizoid, and is pretty much seen as such. He rarely goes out on a limb on intuitions. On the other hand, Moriarty, his evil brother that is only a figment of his imagination, is quite schizotypal. And in that story, where we learn about Moriarty, Sherlock Holmes is doing a paranoid psychosis. It is blamed on cocaine in the book though. My guess is that Conan Doyle was schizotypal himself. He had a lot of interest in the occult and many things. While Holmes is pretty down to Earth, the mysteries he solves are quite fantastical in many instances.
I don't know enough about the life of Isaac Newton and never read any of his work, but I would not be surprised at all if he was schizotypal. I would not take too much weight in the fantastical part of the schizotypal criteria to guess that. It is overrated, IMO. Emotional detachment, overly thinking, withdrawal, lack of trust and unconventional behavior are much more important. The people that actually believe in fantastical stuff are rarely the schizotypal. Schizotypal merely understand and create those things and they mean something by it, usually by analogy.
Take the alien/UFO thing. It is an analogy of feeling alienated from the others. The others are the aliens. While daydreaming, a schizotypal might say that he is being watched by aliens, or that he hears alien voices. It may be tongue in cheek, or it could be due to a psychosis, where it becomes a lot more real. But it means something quite real, generally speaking, but the way to convey it is idiosyncretic.
"In psychiatry, the term means a specific and unique mental condition of a patient, often accompanied by neologisms"
But those that think there are aliens somewhere on other planets that come down to make experiments and mutilate cows are some other people, most of the time. It is too realistic an interpretation to be of any mental value for a schizotypal. Conspiracy theories are not part of the trait.
It is better to be the widow of a hero than the wife of a coward.
