Kung Fu Hustle makes references to a wide range of films,
animated cartoons,
wuxia novels, anime and other sources. Crocodile Gang leader said, "No one shows in the movie theater on Sunday. I will rather do any business than the movie business", before he was ambushed by the Axe Gang. In reality, its actor Feng Xiaogang, is a very famous movie director in China, who made dozens of big box offices. The housing arrangement of the Pigsty Alley is similar to that of a 1973 Hong Kong film,
The House of 72 Tenants. A possible real world reference for Pigsty Alley is "
Kowloon Walled City" in Hong Kong, a former slum in central Hong Kong. There are two references to Chow's previous hit film,
Shaolin Soccer: When Sing arrives at Pigsty Alley, he plays skilfully with a soccer ball, then says, "You're still playing football?". The second reference is the scene in which a clerk beats Sing up on a bus. The clerk also appeared in
Shaolin Soccer as the leader of an opposing team who used hidden weapons to beat up the Shaolin soccer team. When Sing challenges a boy in the Pigsty Alley, Sing calls him "The Karate Kid", a reference to
the 1984 film of the same name. During the altercation between Sing and the hairdresser, the hairdresser states, "Even if you kill me, there will be thousands more of me!". This is a reference to a famous quote made by
Lu Haodong, a Chinese revolutionary in the late
Qing dynasty. The scene in which Sing is chased by the Landlady as he flees from the Alley is a homage to
Wile E. Coyote and the Road Runner, characters in the
Looney Tunes cartoons, even including the pursuer's (the Landlady's) ill fate. During the opening scene in which the leader of the Crocodile Gang is killed by Brother Sum of the Axe Gang, in the background a poster for the 1939 film
Le Jour Se Lève is visible. In the scene in which Sing robs the ice cream vendor, a poster for the 1935 film
Top Hat is in the background. As Sing arrives at the door to the Beast's cell in the mental asylum, he hallucinates a large wave of blood rushing from the cell door, similar to a scene in
The Shining. The Landlady says at one point, "Tomorrow is another day", which is a line from the 1936 novel
Gone with the Wind and its
1939 film adaptation. A major element of the plot is based on the Famous wuxia film series
Palm of Ru Lai (), released in 1964. Sing studied the fighting style used in
Palm of Ru Lai ("
Buddhist Palm style"), from a young age and used it at the end of
Kung Fu Hustle. In reality, the Buddhist Palm fighting style does not leave palm-shaped craters and holes on impact. Instead, the user delivers powerful punches using his palm. The Beast's name in Chinese,
Huoyun Xieshen (; Evil Deity of the Fiery Cloud), and the fight with the Landlady and her husband are also references to the
Palm of Ru Lai, in which a mortally wounded master strikes the patterns of his art's final techniques into a bell so that his apprentice can learn from it.
Kung Fu Hustle also contains direct references to characters from
Louis Cha's wuxia novels. For example, the landlord and landlady refer to themselves as
Yang Guo and
Xiaolongnü, the names of characters in Cha's
The Return of the Condor Heroes, when they met the Beast. ''.|280px|right References to gangster films are also present. The boss of the Axe Gang, Brother Sum () is named after Hon Sam / Hon Sum (), the triad boss played by
Eric Tsang in
Infernal Affairs. The Harpists imitate
The Blues Brothers, wearing similar hats and sunglasses at all times. When they are flattered by the Axe Gang advisor, one of them answers, "Strictly speaking we're just musicians", similar to a line by Elwood Blues. When Donut dies, he says, "
In great power lies great responsibility", a reference to 2002's
Spider-Man, said by
Uncle Ben before his death. Afterwards, with his dying breath, Donut gets up, grabs the Landlord by the shirt and utters in English, "What are you prepared to do?", a nod to
Sean Connery's character Jim Malone in
Brian De Palma's 1987 film
The Untouchables. The dialogue that the Beast says while negotiating with the Axe Gang for killing the Landlady and Landlord—"...then young friend, I will make an offer you cannot refuse" it is a reference of the dialogue from the movie of 1972s
The Godfather. The final fight between Sing (who has been reborn into "the one", which pays homage to Bruce Lee by wearing his costume in
Enter the Dragon and using his fighting style) and the hundreds of gangsters imitates the fight between
Neo and hundreds of
Agent Smiths in
The Matrix Reloaded. == Releases ==
