Remember, even the movie rights to a book must be bought from the copyright holder, in spite that the movie will eventually share little more than the title and name of the main character with the book.

Not really, there is no such thing as a "movie right". If you need it, it is because you would otherwise infringe on for example a copyright or possibly a trademark. In your example, only using the title and nothing much else, it would then possibly be due to trademark issues. I really can't say if books and movies end up in the same category for trademarks, but I assume they might and hence IF trademarked, you might need to get a license for that.

If you use a far larger part of the book, story, context, characters and so on, then it would either be a direct infringement or you might end up with derivative works which again would make it impossible to really do much with the film without the original copyright holders permission. But just title and name of a character? Should be no problem at all.
