My bad... I should not have steered this thread into Trump territory.
My favorite Reiner films are "Stand By Me", "When Harry Met Sally", and "The Princess Bride". Although I didn't "get" it when the movie first came out, I've really grown to love "This Is Spinal Tap", too
Although I loved his Mike/Meathead character in "All in the Family", my favorite of his acting roles was Sheldon Flender in "Bullets Over Broadway".
Goodness, that man's talent will certainly live on.
