The follow-up to Matthew Vaughn's adaptation of Mark Millar and John Romita Jr's comic book series was confirmed earlier this year for a potential May 2013 release.
Superbad star Mintz-Plasse has now offered his thoughts on the project, promising that the film will live up to its predecessor.
He told Collider: "It's super-violent and bloody and funny and it's got a great cast. I'm really excited. I fly out to London in a week to get started... on rehearsals and wardrobe and stuff and then I think we start shooting September.
"It's going to be busy because I'm flying back and forth because I'm shooting a show for CBS as well, so I'll be shooting a couple of weeks September, fly back, go out again in October for like a week, come back, and then go out again in November for a couple of weeks."
The 23-year-old also addressed the issue of Hit-Girl's age, since actress Chloe Moretz - who will reprise her role as the young schoolgirl - is now 15 years old.
"I had no idea if [the sequel] was going to happen," Mintz-Plasse said. "It didn't seem like it, especially now that Chloe is like, what, is she 37 now? But no, they wrote an incredible script.
"I think she's going into 9th grade in this which is really smart. They didn't keep her 11 as she was in the first one. They kind of aged it up a bit."
Jeff Wadlow will take over as director from Vaughn, and has also penned the script.
Aaron Taylor-Johnson will return as the title character, while Big Daddy actor Nicolas Cage is also rumoured to feature in a cameo role.
