After watching Kick Ass, I do have reminiscences of the following:
1) "Mystery Men" - The "cannot make it" heroes that eventually saves the day.
2) "Kill Bill" - The gore & stuff by movie directed by Quentin Tarantino. With Uma Thurman as the killer bride who avenges (goes on a killing spree with her samurai knife) for the deaths of her unborn baby & all the people that was killed at her wedding by Assassin chief (ex-lover or something) - Bill (David Carradine, star of 'Kung Fu') who "hanged" himself in a luxury hotel suite in Bangkok.
3) "Speed Racer"- Sound Track & the comic book effect.
4) "Leon the Professional" - action thriller by French director Luc Besson. It stars Jean Reno, Gary Oldman, and a young Natalie Portman in her feature film debut. Somewhat Hit Girl (Chloe Moretz) & Big Daddy (Nicolas Cage) liken Mathilda (Natalie Portman) & Léon (Jean Reno). Similar to Hit Girl of Kick Ass, Mathilda pairs up with Leon to avenge the deaths of her loved ones.
Below are trailers for Kick Ass the Movie & "Leon the Professional" :
