As is the norm with most soundtrack singles, the video features intercut scenes from the film. The soundtrack song "Kick Ass" has received positive views by many websites such as Popjustice.com and Digitalspy.co.uk The song Stand Up by the Prodigy features in both the Teaser Trailer and Red Band Trailer. Songs in the film not in the soundtrack include "In The House - In A Heartbeat" by John Murphy, from the 28 Days Later soundtrack. This piece was used in the warehouse scene.
The rights to a film version of the comic book were sold before the first issue was published. Vaughn notes that, "We wrote the script and the comic at the same time so it was a very sort of collaborative, organic process. I met [Millar] at the premiere of Stardust. We got on really well. I knew who he was and what he had done but I didn't know him. He pitched me the idea. I said, 'That’s great!' He then wrote a synopsis. I went, 'That’s great, let’s go do it now! You write the comic, I’ll write the script.'" “ With Kick-Ass, the book's just out and now the movie's out six weeks later. And I think that's the way things are going to go now, because to go to Marvel's B and C-list characters and try to get movies out them – what's the point of that? ” —Mark Millar The comic was written at the same time as the script. Millar commented that screenwriters Jane Goldman and Vaughn had made a "chick flick", having placed more emphasis on the character emotions, and particularly in having softened the character of Katie Deauxma. The film was independently financed. Vaughn initially went to Sony, which distributed Layer Cake, but he rejected calls to tone down the violence. Other studios expressed interest but wanted to make the characters older. Vaughn believed enough in the project to raise the money for the project himself. In an interview with Total Film, Aaron Johnson confirmed that the film stays true to the adult nature of the comic series by featuring a large amount of profanity and graphic violence and it received an R rating by the MPAA and a 15 rating from the BBFC. Director Matthew Vaughn felt the 15 certificate was about right and expressed some surprise at the film having received a PG rating in France. Filming locations include Hamilton, Ontario, Canada, at Sir Winston Churchill Secondary School, and various locations in the UK, including Elstree Studios.
Nicolas Cage as Damon Macready/Big Daddy. Brad Pitt was considered for the role. Vaughn described Cage's performance as a little bit Elvis and a little bit Adam West. A character in the film even says his costume looks like Batman.
Chloë Grace Moretz as Mindy Macready/Hit-Girl. Vaughn commented on the maturity of Moretz, and she told him having four older brothers, there was not much in the script she had not heard before.
Dave Lizewski (Aaron Johnson), a typical teenage boy, wonders why no one has ever decided to become a real-life superhero like the heroes in the comic books. His friends at a comic book store told him that if anyone did become a superhero, they would get their ass kicked, and probably be killed. Despite this, Dave decides to create a superhero costume for himself and become a masked crimefighter. Dave fails at his first attempt to fight crime – he is beaten, stabbed, and hit by a car. He convinces paramedics to say nothing of his costume and pretends he was brought in naked. In hospital for several weeks he is left with metal holding his bones together which he says makes him look like Wolverine. He has also suffered nerve damage which gives him an above average ability to take a beating. When he returns to school, his longtime crush, Katie Deauxma (Lyndsy Fonseca), seems more interested in him. His friends explain she thinks he is gay and wants to take care of him. Lizewski goes along with this in an effort to spend time with her. Dave remains undeterred by his earlier setback, and ends up intervening in a gang fight outside a diner. Dressed in costume and using two modified night-sticks, he fights off three men. As the fight ends, a man who has been recording the event on his phone, asks Dave who he is, and he replies: "I'm Kick-Ass". The video is posted on the internet and soon becomes an internet phenomenon, making Kick-Ass an overnight sensation. As Kick-Ass, Dave sets up a MySpace account, so people can contact him for help and is overwhelmed with responses. While spending time with Katie, she admits that she was being harassed by a drug dealer, and Lizewski convinces her to ask Kick-Ass for help. He investigates and ends up in an apartment full of violent lowlifes who try to kill him. He is rescued by a costumed, sword-wielding young girl named Hit-Girl (Chloë Grace Moretz), who kills all the attackers and then leaves to join her father, Damon Macready (Nicolas Cage), whose alias is Big Daddy. Hit-Girl (Mindy Macready) jumps across the rooftops and tells Kick-Ass to follow her, but he is afraid to jump, so they leave without him. Later Kick-Ass is visited at home by Hit-Girl and Big Daddy who have tracked him from his MySpace account. Hit-Girl and Big Daddy inform Kick-Ass that they can work together, and should he need help then he should set his MySpace status to "on vacation" and they will arrange a visit. Meanwhile, local crime syndicate leader Frank D'Amico (Mark Strong) hears of the deaths of many of his men, with many people believing that the new star, Kick-Ass, is responsible. In searching for Kick-Ass, D'Amico kills an impersonator whom he believes is actually Kick-Ass. Running out of ideas, his son, Chris (Christopher Mintz-Plasse) suggests that he set up a new superhero persona ('Red Mist'), enticing Kick-Ass into meeting him. At first, Red Mist attempts to lead Kick-Ass to a warehouse to be killed by D'Amico's men. They arrive to find it on fire, and the men are dead; Red Mist retrieves secret surveillance footage which shows that Big Daddy is responsible for the attack. Red Mist asks Kick-Ass to call Hit-Girl and Big Daddy for help, and they arrange to meet at a safe house. As soon as they arrive, Hit-Girl is sitting on a window ledge and Red Mist shoots her, propelling her out of the window and on to the floor below. Kick-Ass and Big Daddy are captured by D'Amico's men and taken to a warehouse where the gangsters stage an internet broadcast, intending to unmask and execute the heroes. After they have been severely beaten and are about to be set on fire, the lights are shot out and Hit-Girl starts a gun battle, killing the villains, but a fire starts and Big Daddy is badly burnt, succumbing to his injuries after a tender moment with his daughter. Kick-Ass tries to convince Hit-Girl to quit, but she is determined not to allow the death of her parents to be in vain and makes one last assault on the headquarters of Frank D'Amico. Hit-Girl enters D'Amico's headquarters and disposes of several guards by posing as a lost schoolgirl. On the upper floor, she quickly disposes of the majority of the guards, but runs out of ammunition and is forced to take cover in the kitchen. Not willing to risk a direct confrontation with Hit-Girl, one of the henchmen grabs a bazooka stolen from Big Daddy's safe house earlier and prepares to fire (saying "Say hello to my little friend!"), but is killed by Kick-Ass, who appears riding a jetpack fitted with two Gatling guns (which was purchased by Big Daddy and Hit-Girl earlier in the film). After disposing of them, Kick-Ass and Hit-Girl move into D'Amico's office, and two separate fights ensue between Kick-Ass and Red Mist, and Hit-Girl and Frank D'Amico. While Kick-Ass and Red Mist fight until they knock each other out, Hit-Girl is overwhelmed by the older and stronger D'Amico. As D'Amico is about to shoot Hit-Girl, Kick-Ass appears with the bazooka and blasts D'Amico out the window, where he explodes in mid-air. Red Mist recovers and grabs his father's sword only to discover that Kick-Ass and Hit-Girl are already leaving. They tell each other their names and say goodbye. Both Hit-Girl and Kick-Ass retire from crime fighting, with Mindy living a normal life and attending the same school as Dave. Another wave of superheroes have been inspired by his exploits. Red Mist is shown donning a new mask and swearing vengeance, saying "Wait 'til they get a load of me".
