Revealing mistake: When Inigo and Westley are duelling, they are making athletic jumps. One does it after the other and when they land you can see the mat wrinkle under the "dirt" on the ground.

More mistakes in The Princess Bride
Vizzini: Inconceivable!
Inigo Montoya: You keep using that word. I do not think it means what you think it means.
Trivia: Mark Knopfler, who composed the music to the Princess Bride, only agreed to do so if Rob Reiner could include the baseball cap he wore in the film Spinal Tap. The director placed the cap in the boy's bedroom, beside the bed.
Question: Inigo shows Westley the sword his father made for the 6-fingered man ("I've never seen its equal"). How did Inigo acquire this sword? You would think that if Count Rugen was prepared to kill Domingo for the sword then he would have taken it with him.
Answer: In the book, Count Rugen told the outraged villagers that Domingo had tried to rob him and he killed Domingo in self-defense. He couldn't very well take Domingo's sword after that.
Answer: When Inigo was a child, Count Rugen came to Inigos father and requested a sword be made for him. When the sword was finished, Count Rugen refused to pay the price he originally offered for the sword. Inigos father refused to hand the sword over so Count Rugen killed Inigos father. Outraged, Inigo took the sword his father made and tried to kill Count Rugen. He has kept the sword ever since so he could use it to kill Count Rugen.
