"Because it's kind of insane. Would the world accept this?
"It makes 'Kick-Ass' look like 'Finding Nemo'.
"It's funny, because Hit-Girl was slightly pre-dated by about a year, before those kick-ass action heroine characters...

"And now I feel is a great time for her, so it could be really interesting."
The first Toronto-lensed "Kick-Ass" feature released in 2010 on a budget of $30 million, earned $100 million world-wide, selling over 1 million DVDs, scoring an additional $24 million.
Toronto-lensed "Kick-Ass 2" on a budget of $28 million, released in 2013, earned $63 million world-wide plus $15 million in DVD sales.
Although those numbers are not blockbuster, there is a dedicated fan-base including director Quentin Tarantino, that supports Chloë Grace Moretz' portrayal as young female vigilante 'Hit-Girl'.
"I'd always planned it as three books and three movies," said Millar about "Kick-Ass".
