Will Smith is set to star in a sequel to his hit 2008 superhero movie Hancock.

Screenwriter's Adam Fierro and Glen Mazzara have been hired to work on the follow-up, which starred Smith as an alcoholic superhero.

It's expected that Hancock 2 will "build on the world hinted at in the first movie".

It's not yet known whether Jason Bateman, Charlize Theron or director Peter Berg will return.
