Thank you marcelb7. List updated.

Thank you Kluge. List updated.

On another note. IMDB claims that for 20 Million Miles to Earth he's uncredited as the Narrator. So if he's not in the credits for that one, the Narrator voice should be listed to to determine if he should still be listed with that movie as an uncredited role or if he should be deleted.
