I just finished watching the last installment of
The Princess Bride: The Home Movie, and there are quite a few amazing appearances in it.
As it turns out, this movie also includes Carl Reiner's last screen performance.
If you have seen
The Princess Bride, you definitely need to watch this version.
(And if you haven't seen the original version of The Princess Bride, you have some catching up to do!)
P.S. I have the right hair for Inigo Montoya (but I think that I would make a great Dread Pirate Roberts).
Update (7/11/20): I really enjoyed this version of the movie. It is kitschy, of course, but it's supposed to be. There are some really cool performances and choices of actors in it. And some cool bits of humor with improved props. It's definitely worth watching. Obviously, it's not polished like the original, but it isn't supposed to be.
