Brad Pitt's character and indecipherable speech was inspired by many critics' complaints about the accents of the characters in Lock, Stock and Two Smoking Barrels (1998). Guy Ritchie decided to counter the criticisms by creating a character that not only couldn't be understood by the audience but that also couldn't be understood by characters in the movie.
When Guy Ritchie told Brad Pitt that he would be playing a boxer, Pitt became concerned because he had just finished shooting Fight Club (1999) and did not want to play the same type of role again. Pitt took the role anyway because he wanted to work with Ritchie so badly.
When Vinny and Sol are sitting outside Brick-Top's Bookies, about to give him the diamond, the man that approaches the car is not really Bullet-Tooth Tony, it was a look-alike. Vinnie Jones didn't show up for shooting that day because he was in jail for fighting the night before.
According to the DVD commentary, Bow, the dog was very difficult to work with. During car scene with Vincent, Sol and Tyrone, the dog was actually attacking Lennie James, and James was actually bitten in the crotch by the dog but didn't suffer any serious injury. The dog was replaced after that incident.
In Guy Ritchie's previous film Lock, Stock and Two Smoking Barrels (1998), there is a scene in which Harry, Barry and Chris have a conversation. Barry says the line. "No, Harry, you can't," which is shortly repeated by Chris, then by both together. This joke is carried over to this movie when Alex and Susi do the same thing with the line, "Yeah, Dad, you told us."
The role of Brick Top was originally offered to Sean Connery. Connery liked the script and was curious to see Lock, Stock and Two Smoking Barrels (1998), so producer Matthew Vaughn hastily arranged a screening for him at extreme short notice. Connery duly turned up and watched the film, before emerging with his judgment: "That is a good film", he said, "and (in a stage whisper) you're not going to be able to afford me." Cue Alan Ford.
During the opening credits, the Hasidic-clad diamond thieves are discussing the Virgin Mary. This is a reference to Reservoir Dogs (1992), where during the opening scene the thieves are discussing the Madonna song "Like a Virgin".
To keep things in order during production, director Guy Ritchie introduced a system of fines on set. There were fines for mobile phones ringing, arriving late, taking naps during shooting, being "cheeky", being unfunny, and/or moaning and complaining. One staff member was even charged for letting the craft service table run out of coffee cups.
Just before Mickey and Bomber Harris begin their fight, Bomber Harris head-butts Mickey just after the bell rings. Mickey recoils checking for blood on his glove and then floors his opponent with one punch. This was a nod towards Lenny "The Guv'nor" McClean when he fought "Mad Gypsy" Bradshaw in an almost identical fight. Lenny McLean worked with Guy Ritchie on Lock, Stock and Two Smoking Barrels (1998) and passed away in 1998.
Vinnie Jones character goes after a dog with a knife to cut him open after swallowing a diamond. In Gone in Sixty Seconds (2000), his character is stopped from cutting open a dog who has swallowed some car keys.
One of the boxers is called Bomber Harris. "Bomber Harris" was the nickname of Arthur Harris, chief of RAF Bomber Command in World War II. The name later appeared in a German Monty Python special (Monty Python's Fliegender Zirkus (1971)) as the name of a man who wrestles himself - Colin "Bomber" Harris.
Throughout the movie, Turkish (Jason Statham) makes comments to Tommy (Stephen Graham) about his getting a gun for protection from "Ze Germans". Graham also played Sgt. Myron 'Mike' Ranney in the series Band of Brothers (2001), although Snatch was released a year prior to the series.
In the scene where Tony asks for a pint of the "black stuff", he is handed a half filled glass. The barman had lifted it to complete the 2nd half of the pour associated with stout, but thought better of it upon noticing the approaching raiders.
The car driven by Tyrone is a Rover SD1. It is the Vitesse version which was the fastest version made. It has a 3.5 litre V8 engine which ran on petrol/gasoline. The car was in production from 1976-1986 and in this time there was a "facelift" updated model as used in this film. The car is driven by the rear wheels and was a favorite amongst police and criminals when they were in production; so much so in fact, that the police started buying second hand cars and converting them for use in the police force when they went out of production. There were many different engines available, such as a 2.3 and 2.6 liter in-line 6 cylinder engine and a 2.4 liter turbo diesel engine, which was revolutionary in the 1980s. After the car went out of production, the design was sold to a company in India and it was re-badged and sold again as the Standard 2000.
The hardcore band "Cold War from Orange County, California" quotes this movie several times throughout their CD "From Russia With Love." Some of the lines quoted are: ("Quote" - Character / Song in which quote is used) "From Russia with love, ah?" - Doug The Head / Love Betrays "Heavy's good, heavy's reliable." - Boris the Blade / Painful Delight "Do you know what "nemesis" means? A righteous infliction of retribution manifested by an appropriate agent. Personified in this case by an 'orrible c*nt... me." - Brick Top / Retrace My Steps
The trivia items below may give away important plot points.
The film's title only appears once throughout the entire movie, where Vinny (Robbie Gee) tells the dog, "Don't Snatch!" as it takes the squeaky toy. It is said to the dog because it's the dog who eats the diamond.
When Mickey "wins" a new trailer van for his mother from Turkish, he specifically picks out "periwinkle blue" as the color. In Psycho (1960), we are told that Norman Bates helped to pick out a "periwinkle blue" dress for his dead mother. Mickey, just like Norman, is also responsible (albeit indirectly) for his own mother's death.
