In fall of 1987, "The Princess Bride" must have struck many Hollywood insiders as a forgettable piece of fluff, a movie that couldn't decide if it was a fairy tale for the kids or a spoof for the grown-ups.

There were early signs of affection for Rob Reiner's PG-rated comedy/adventure: A week before its Sept. 25 opening in nine U.S. theaters, it won the audience prize at the Toronto film festival. During its 11-week U.S. theatrical run, it rose as high as No. 3 on the box office list. But at the end of the year, it was No. 41 on the money list, a notch above "Revenge of the Nerds II: Nerds in Paradise."

Twenty-five years later, "The Princess Bride" is one of the standouts of the 1987 crop. Its DVD sales remain hearty. It's quoted widely, and not just on "Mystery Science Theater 3000": "Inconceivable!" "Have fun storming the castle." "You killed my father. Prepare to die."
