Yes. I agree, and it's stated in the documentaries in the DVD. William Goldman and Rob Reiner demonstrated a true partnership in this project. Goldman had Andre the Giant in mind for the role of Fezzik.
In the documentary, Rob Reiner mentioned that mob wiseguy approached him at a restaurant and said to Reiner, "You killed my father. Prepare to die."
Gotta love it.
The Princess Bride is a movie that will be timeless for all generations.
