Question: Where were the cans for fuel for the automobiles?
Question: The man who goes into the bunkhouse to get a gun and gets shot in the stomach in the beginning is the same one in the gray suit acting drunk in the saloon fight big Jake has.
Question: At the beginning of the movie I counted 9 bad guys. We only see 1 die, then there are 6 - what happen to the others?
Question: At the beginning of the move it is established that Big Jake has not seen his sons for 10 years, but it appears he is close enough geographically to be found, summoned and arrive before the bad guys can get more than a days' ride away from the ranch. Was he really that bad of a dad or is his arrival at the ranch a bit too magical?
Answer: He has been gone for 10 years but knows "Juan and the little boy", not 10 years old I assume.
Answer: It doesn't help explain locating Big Jake or time involved, but as to helping some with the quickness of him coming to help, remember he came in on a train, he didn't ride back home.
Question: The term highway robbery was used by the sheep herder; was highway a word at the time?
Answer: Yes, it existed then. The word "highway" originates from the Old English heahweg, a compound of high and way. The "high" referred to many early major roads, especially ones built by the Romans, which were physically elevated mounds of dirt to protect them from flooding. The common term was transported to the American colonies. Over time, it evolved, with "high" meaning "main" or "major," as in "high street" or "high road." "Highway" became a general term for a major public route.
Question: What is the weight of the million dollars in $20 bills?
Answer: A U.S. bill weighs roughly 1 gram so that about 454 bills (regardless of denomination) weighs 1 pound. It takes 50,000 $20 bills to equal $1M. Which is about 110 pounds. Of course this is freshly minted weight, so any debris and anything used to secure the bills would increase that weight).
But you also have to take into account the weight of that strong box. I have seen replica boxes, and even they were quite heavy, so I'm sure the real thing would have weighed quite a lot. Then you have to add the actual weight of the currency.
Answer: According to Wikipedia, the shootout at the ranch, both Devries brothers are killed by Jeff McCandles, before being shot himself. The rest die at the end of the movie.
You only see the older brother shot by Jeffrey before being shot himself. I only assumed young Billy stayed behind to help his brother.
