Question: Is there any reason why Luke believes what Darth Vader says when he tells him that he is his father?
Answer: The vision Luke sees in the cave on Dagobah is a clue to this. Luke is realizing he has a lot more in common with Darth Vader than the idealized father he'd always imagined. When Vader tells him he's his father, Luke doesn't want to believe it, but he simply can't deny that it feels much more true that his father would be someone passionate and reckless like himself rather than someone who exemplifies a noble Jedi, which feels like an obvious myth in hindsight.
Question: What exactly was the enormous creature that came out of the ground and attacked Flash in the forest?
Answer: Spider.
Question: Did John Belushi do all the dancing, especially the turnovers in church, by himself or was it a double?
Answer: It was a double, and the "making of" documentary on the DVD shows this.
To be fair, John did do a lot of flips and dancing as Jake; just not all of them in the movie.
Question: Not being a gambler, the terms they use has always confused me. For example at the end the Black Widows tell Beekman that he still owed them $0.70 on the dollar. What does this mean? How much does this add up to?
Chosen answer: This means 70%, ie. for every dollar they are owed they will only recieve 70 cents.
Question: In the movie, Buford shoots two flying bottles whilst holding the gun at his hip. Is that even possible?
Chosen answer: Technically, yes, but no matter how adept the shooter, such a trick would always rely more on luck than skill. Shooting from the hip makes it impossible to aim any better than "in the general direction of the target."
Chosen answer: He "searched his feelings" as Vader instructed; he reached out with the Force and felt the truth of the statement.
