Did you ever see the 1984 movie, Sarah?
I always thought that the movie might've been better if Ridley Scott had done it instead of David Lynch. Lynch didn't really capture the novel correctly, nor was he able to translate it to the screen well enough for audiences. I wish Ridley had done Dune instead of that awful Legend movie with Tom Cruise, but perhaps after Alien and Blade Runner he wasn't in the mood for another science fiction movie.
Oh, and Patrick Stewart/Charles Xavier was in the original Dune movie.
So both Charles Xaviers were in the Dune films.
