Question: What was the mixture that Mississippi gave to JP Harra?
Answer: It was an old folk remedy for a hangover. It was supposed to make someone unable to drink liquor for a short period of time. The fictional potion's ingredients were not specified.
The ingredients of Mississippi's hangover concoction are very surely in the scripted dialogue. Mississippi: "Johnny Diamond had a recipe. Let's see. Cayenne pepper, mustard-the hot kind, ipecac, asafetida, and oil of cloves or was it? No, it was croton oil." Bull: "Croton oil?! I'll be a suck-egg mule. You know what that mixture'll do to a fella?" Mississippi: "Guaranteed kill or cure." The final ingredient is gunpowder.
Answer: Croaking oil, gunpowder, hot mustard, ipecac, asafetida.
Question: At the end of the film Blondie, sitting on the horse, turns around, aims his rifle, fires, and severs the rope with a single shot. Lets face it, that rope would be a very small target, and difficult to hit with precision, even from ten or twenty feet, and Blondie is now so far from Tuco that he would no longer even be able to see the rope. Could anyone hit such a small target from such a distance with such incredible accuracy?
Answer: There's a show called "Hollywood Weapons: Fact or Fiction" which dealt with this exact question (s01e03). Blondie is roughly 200 yds away. In the show the host didn't hit the rope, but only missed by an inch on his first attempt. I definitely think an expert Sharps Rifle shooter could make the shot. The issue however, is the bullet would most likely not actually slice the rope apart as seen in the film (they fired the Sharps at point blank and the rope remained partially intact still). They also tested shooting a hat off someone and (as expected) the bullet just goes right through the hat without lifting the hat at all.
That was another thing that puzzled me. On several occasions in this film, Tuco is suspended from a rope, and Blondie cuts the rope by firing a bullet at it, (I think Clint Eastwood repeated the trick in "The Outlaw Josey Wales"). But if you fired a bullet at a rope holding a (rather large) person like Tuco (or a similarly heavy weight), even at close range, would it really sever the rope? I will have to look out for "Hollywood Weapons Fact Or Fiction." I hope they only used a dummy or a model to re-create the shooting feats. I don't think I would have liked to have been hanging on a rope while somebody fired bullets at me to see if this would sever the rope, or to stand there while they fired bullets into my hat to see if they could lift it off my head.
Answer: Probably not, but remember...this is a movie, a western at that and they typically have over the top action to excite audiences. Kinda like how it's impossible to shoot someone's hat off without harming them. It's all for show.
Question: Who was the $10,000 for?
Answer: For each member of the Professionals.
Answer: The prime ingredient was Ipecac, a nausea-inducing compound (still used today) which so inflames the stomach lining that it's impossible for the patient to hold anything down. Hot mustard in large doses has a similar effect. The other ingredients (croton oil, cayenne pepper, etc) acted as powerful laxatives, so the entire gastrointestinal tract is evacuated in short order. The gunpowder was a fantasy ingredient, no doubt, as gunpowder is known to cause gangrene of internal tissues.
