The biggest hole in the entire story: Chekov is listed in the beginning of the movie as merely a "soldier" and is later referred to by Smecker when he says "not like those other mob peons in the alley." But if Chekov and his buddy were mere peons, they wouldn't have been invited to the big meeting at Copeland Plaza. Smecker said the nine men in that room were all big-timers, and "I have a dossier on every man in this room." [Chekhov was called to the meeting because he was a soldier, the big-timers at the meeting needed protection, hence calling in a soldier. We see the exact reason they needed a soldier because the Italian mob sent a man to kill everyone in the room, even if he couldn't have possibly killed all of them.]

When the Saints call the FBI Agent on the phone, they are shown calling from a payphone to a payphone. During that scene, they cut to a shot of the agent's business card, where the only phone numbers listed are an office number and a cell number. [It is assumed that the call would be payphone to payphone so as to be untraceable. I'd assume also that they called the work phone first.]

In the scene in which Conner jumps off the building after he drops the toilet, we see him fall slow-motion beside the Russian - his legs do not touch him, but when we see the Russian dead, he has foot-prints on his back. [You see him step squarely on the Russian's back later in the scene (after the slo-mo part).]

Each time the Saints kill someone, they say a prayer. Towards the end of that prayer, they pull the hammers back on their guns to cock them. There are two problems with this: 1) On an "auto-loader" (non-revolver) with a hammer, the hammer is not intended to be cocked manually, but rather cocked when the slide is racked. 2) Racking the slide chambers a round and cocks the hammer back. While it is possible to have had a round in the chamber and the hammers forward, they would have had to rack the slide, then (very unsafely) lower the hammers onto the firing pin/firing pin mechanism, creating a scenario where an accidental discharge is much more likely. (i.e. when wrestling in the vents). [Although its true that on an automatic the slide typically cocks the hammer, they also can be cocked manually. Additionally, many pistols have what is called a "decocker" that removes the pin and lets the hammer fall (decocking the gun without danger of firing the round see: H&K USP). Its easy to concieve that these guns had decockers. Additionally, its very common to chamber your rounds then lower the hammer. Many pistols using double action (being able to fire with the hammer forward or back) do this, and it is considered much safer, because the trigger pressure necessary to pull the hammer back and then release it is significantly higher than to simply release a cocked hammer.]

As the three are having their wounds sealed, Norman is having his done first. As Sean Patrick is sealing the arm, Rocco is holding Norman down. You can see that Rocco's finger has almost entirely stopped bleeding already and is wrapped. Yet Rocco is the next one, getting his finger sealed. [Of course Rocco's thumb is bandaged. When your finger gets shot off, there tends to be a lot of blood, so they wrapped it to stop the bleeding. Plus, he had to help restrain one of the brothers, and that would be quite painful with an unwrapped finger nub.]

As Agent Smecker and the others are investigating the multiple-murder scene in the Copley Plaza hotel room, one of the others is suggesting that one man shot with two guns. Right before the flashback at the end of this scene, Agent Smecker says, "You telling me that one guy came in here and killed eight men with eight extremely well-aimed shots?" Yet in the very beginning of the same scene, he said there were nine. [There were nine killed, yes, but the head guy was killed last, execution style. The other eight were killed first, and quickly, so Smecker was saying that there was no way one guy could storm in there and kill THOSE eight with extremely well-aimed shots. The execution of the head guy wasn't "well-aimed", it was point blank.]

After the two brothers kill the 9 guys in the hotel room, we see Connor putting some pennies on the bald guy's eyes. However, if you look closely, you can see the pennies move because they are making the guy blink a whole lot. [The pennies shake because the Irish brother is moving the body. He is rearranging the bodies arms and is also sitting directly next to him on the couch, so if the brother made the slightest movement the body would shake.]

It seems to be a contradiction that the brothers would seek to "destroy all that which is evil," yet have a friendship with Rocco whom they know is in the Mafia. [But Rocco himself is not evil. He is only a numbers runner who doesn't even like the other members of the mafia such as Vincenzo or Yakevetta.]

While Connor is attempting to rip the toilet out of the floor, he almost knocks the lid off of the tank. In the next shot, as he is standing up in slow motion, the lid is back in place. [Almost is the key word here because if you watch in slow motion he ends up pushing it with his shoulder back onto it.]

In the scene where the Russians are being yelled at in the hotel by their leader, his name and surname are written - and his surname ends with an "a." Only female surnames end with an "a" in Russia. [In the movie it does give the surname and the ending with an "a" is ok. This entry is thinking of the patronymic were it must end with an "a" to be correct for a female and a "vich" for a male.]

At the beginning, the MacManus brothers are attending a Catholic mass. The priest is saying the Our Father, and concludes it with "For thine is the kingdom, the power, and the glory for ever and ever." However, Catholics do not include this line when they say this prayer - only Protestants say this. Also, the prayer is never said before the priest gives his homily as it is in the movie. [I go to Catholic Mass every Sunday and they do include this line in the Lord's Prayer.]

After the stand-off with the Duke, Murphy is the first of the three to have his wound sealed. Conner removes the iron from the stove, but in the next shot it is clear that there is blood already on the tip, and only the tip, of the iron, as if a wound was sealed before him. [The blood on the tip could easily be Murphy's, as Connor may have already put it to the wound before the shot, and it didn't quite do the job so they had to do it again.]

In the scene that Rocco shoots the cat, Norman Reedus has a cigarette when he jumps away from the table but when he checks himself, the cigarette is gone, then it reappears. [The cigarette is visible in his right hand, while he rolls over the chair and when he checks Sean and himself. He starts to switch hands right before they show the shot of the "cat" and it rests in his left hand when he points in disbelief.]

As the toilet (which Connor dropped off the roof) hits Ivan Checkov's head, it is clear that it is a fake toilet. You can see a top, flat part of the toilet which does not exist. [The top part of the toilet detaches from the main part as Conner drops it, and nearly hits Murphy on the head hence why he ducks forward.]

After they cut themselves free from the rope in the hotel scene, they pull the rest of the rope out of the ceiling. How was the rope strong enough to hold two men and weak enough to be barely yanked out? [The rope could simply have formed a loop(before being cut). Cutting the rope then "opens" the loop and the rest of the rope can easily slide down.]

After their stand off with the duke, they seal their wounds with an iron, but however I must ask why heat an electric iron on the cooker? [The iron wouldn't be hot enough if they only plugged it in. Instead, they heated it up on the stove to get it really hot to seal their wounds.]

When the brothers and Rocco enter the strip bar, there is a woman sitting behind them obviously able to see what they are doing. If she had seen three men with masks on and guns drawn don't you think she would have said or done something? [Rocco: (With his hand over her mouth and gun pointed at her head) "You scream, you're dead." He then has his hand over her mouth until she passes out. So no, I don't think she would have said or done something.]

When Rocco puts on his mask at the Sin Bin, Murphy says he looks like MushMouth from Fat Albert, but it's Dumb Donald that wears the mask in the TV show. [Many people in real life think MushMouth wore the mask for whatever reason. Since it does happen in real life happening in the movie is a character error but not a movie mistake as it is true to life.]

At the hitman´s house, one of the MacManus brothers rolls a white cue-ball to Rocco, Rocco grabs it and uses it to smash in the hitman´s head, but now the ball is red. [That's blood for you...]
