Apparently the TV series Game of Thrones cost just under $600m to produce[1], and George R. R. Martin earnt something like $100m from royalties as its original author[2]. Although access to the author for advice and publicity must be valuable, that is nonetheless a very large proportion of the profits that I'm sure many studios would rather not have to share!
