The long-discussed sequel to 2008's Wanted is still in development, with producer Mark Platt telling ComingSoon that, "We have a script that's getting pretty good."

Loosely based on the 2003 miniseries by Mark Millar and J.G. Jones, the original film starred James McAvoy as a frustrated accountant who discovers he’s the son of a professional assassin and decides to join the thousand-year-old secret society for which his father worked. Angelina Jolie played his mentor Fox, who died in Timur Bekmambetov's action thriller, which Platt acknowledges created a hurdle for a follow-up.

“To do a sequel when it wasn’t really set up for a sequel – one of our main characters dies in it," he says. "You don’t want to just retread a similar story, but when we get the script to a certain bar, there will be a sequel. It’s taken a while because it’s challenging, as I said, because we lost a main, main character, so where that James McAvoy character goes now … we have good ideas, though. It’s coming along.”

Millar remains involved in Wanted 2, but Platt says he isn't penning the screenplay.

The writer's ext big-screen adaptation is the Matthew Vaughn-directed Kingsman: The Secret Service, which stars Colin Firth, Samuel L. Jackson, Mark Strong, Taron Egerton and Michael Caine. It opens Feb. 13.
