Columbia has set writers Adam Fierro and Glen Mazzara to pen Hancock 2, the sequel to the Will Smith superhero movie, which grossed $624 million worldwide last year, according to The Hollywood Reporter.

The plot details are being kept under wraps, though the scribes will work with Smith and director Peter Berg to build on the world hinted at in the first movie.

The original starred Smith as a boozy, irresponsible superhero who undergoes an image makeover by a public relations man. It later is revealed that the hero is part of a line of immortal beings who have been around for more than 3,000 years and begin to lose their powers when in proximity to fellow immortals.

Hancock, originally titled Tonight He Comes, took more than 12 years to make it to the screen; the sequel will be on a faster track.

No production date has been set.
