In 2010, Chloë Grace Moretz portrayed Hit-Girl in Matthew Vaughn’s action film Kick-Ass, an adaptation of the comic book series by Mark Millar and John Romita Jr.

Born on February 10, 1997, Chloë had just turned 13 when Kick-Ass was released in April 2010. Filming began in September 2008, making her 11 years old at the start of production.

Preparation for the Role of Hit-Girl

Before filming, Moretz underwent months of training with Jackie Chan’s stunt team and a circus school in Toronto, and she performed most of her own stunts on location.

Because of her young age, Moretz’s role in the violent film sparked controversy. However, she received widespread critical acclaim for her performance. Renowned film critic Roger Ebert gave the film only one star but praised Moretz’s “presence and appeal.”

Aspiring for an Action Role

A month before receiving the script for “Kick-Ass,” Chloe Moretz expressed a desire to her mother for an Angelina Jolie-type action role for kids.

“It’s a movie and it’s not real. It was really funny because about a month before we got the script for the movie, Wanted came out. I was in the car with my mom, and this is a true story, no faking or anything, I was like, ‘Oh my God, mom, I really want an Angelina Jolie action kids role!’ She was like, ‘They don’t make kids movies like that.’”

“A month later, we got a script for Kick-Ass and my mom read it, and she was like, ‘Oh my gosh, Chloe. You’re gonna love it! It’s an amazing role and exactly what you’ve been wanting.’ From the get-go, we wanted the film really badly. I read it and I was like, ‘I have to be Hit Girl!’ I did the whole process, and eventually I booked it and I freaked out. I was screaming for two days straight.”

Challenges in Producing ‘Kick-Ass’

Matthew Vaughn encountered several rejections from studios before raising the budget for “Kick-Ass” at a dinner party and making the movie independently. He later sold the film to Universal for a higher price than initially requested.

The producers faced opposition from multiple studios who demanded that Hit-Girl be removed from the film or made nineteen years old.

Staying True to the Character

It was Chloë Grace Moretz’s mother who suggested that they stay true to the comic book and have her daughter use the word “cunt.”

Chloë Moretz’s Perspective on Her Role

“It’s a movie; it’s not me,” Moretz explained in an interview. “If I ever uttered one word that I said in [‘Kick-Ass’], I would be grounded for years! I’d be stuck in my room until I was 20! “I would never in a million years say [what Hit-Girl says in this film],” she laughed.

“I’m an average, everyday girl; when I act with my friends, I’m totally immature. … I have to go to bed at 9:30. If I’m up late on the computer, I lose it for two months.”

Meanwhile, the lead character’s name, Dave Lizewski, was selected at a charity auction run by Kick-Ass co-creator and writer Mark Millar before the first issue of the comic book was published. The auction winner chose to use his own name for the character.

Following her breakout role as Hit-Girl in Kick-Ass, Chloë Grace Moretz quickly became a fashion icon, known for her bold and unique style choices. As her career progressed, so did her fashion evolution, showcasing her versatility both on-screen and on the red carpet.

For the 6th annual party on the High Line, the then-19-year-old actress chose a punk-rock chic outfit from Coach’s Resort 2017 collection.

She wore a high-waisted black leather mini skirt featuring silver-tone zippers, black-and-red chains, and a quilted waistband.

The thigh-grazing number didn’t flatter the young star’s upper figure but highlighted her toned legs. Chloe balanced out the edginess of the skirt with a sheer floral top. She then accessorized with minimal jewelry, allowing her outfit to do the talking.

The “Kick-Ass” star wore her blonde tresses down and added a stylish quiff to play up the punk vibe of the look.
