“Our once and, hopefully, future Hit Girl. Watching a pint-size eleven-year-old murderize a whole roomful of knife- and gun-wielding thugs is quite something, but the gleeful, little-girl smiles she shoots at Aaron Johnson’s Kick-Ass elevate the character from gimmick to iconic. She is so much more than just a Powerpuff Girl brought to life – and that’s why you can expect Comic Con ‘10 to be overrun with thousands of purple-haired, black-masked tributes. She will deliver us from Bella Swan.
And Moretz is no precocious Dakota Fanning-esque child star: she’s got the natural charm and self-posession of a young Jodie Foster.”

“The engine behind the mayhem is Chloe Moretz, who basically steals the show as a miniature killing machine. As previously mentioned, Kick-Ass is violent, and the film always seem to place Hit Girl in the middle of the hardest violence. She is shown gunning people down, shooting them in the face, cutting off their legs with swords, and stabbing them with knives. Casting such a young actress in this role may seem questionable, but this character is part of the overall risk taking that gives Kick-Ass its edge.”
- Rodney Perkins, Twitch Film

“Chloe Moretz has to be the star of the show. She plays Hit Girl perfectly with the ability to get every one liner and she pulls of the action every time. I’m sure that there will be a flood of Hit Girls on the Cosplay scene very soon!”
- Lord Shaper, The Furnace

“Chloe Moretz is truly impressive at Hit Girl, but it’s the little grace notes that impress me more than the acrobatics and the bloodshed.”
- Drew McWeeny, HitFix

“But all of their performances seem supporting to that of Chloe Moretz. Fresh of her role as the sweet, straight-talking little sister in 500 Days of Summer, Moretz lights up the screen as Hit Girl. She’s crass, aggressive and whip-smart. It’s a brave choice for any 13-year old actress — a movie in which she says all the naughty words our parents taught us not to say, even the “c” word — but she commits to the role and drives it home with charisma that is far beyond her years.”
- Neil Miller, Film School Rejects

“But no one could rip their eyes away from little Chloe Moretz when she was running her blades through the backs of drug dealers. She was fantastic. Her chemistry with her father, played by Nic Cage, was spot on; her fight scenes were expertly choreographed, and she knew how to kick ass on screen. Everyone is going to be talking about her attitude, and everyone will be dressed like her for Halloween. Her screen time was nothing short of delightful.”

“Make no mistake about it, Chloe Moretz (500 Days of Summer) owns this movie. She may only be 11 years old, but her performance as Hit-Girl is spunky, sassy, and exciting. Hit-Girl is poised to become a new comic cult icon, and Kick-Ass is quite simply a rollicking good time.”
