What the deep voice says:
"There are heroes... there are superheroes... and then there's Hancock. With great power comes great responsibility – everyone knows that – everyone, that is, but Hancock. Edgy, conflicted, sarcastic, and misunderstood, Hancock's (Will Smith) well-intentioned heroics might get the job done and save countless lives, but always seem to leave jaw-dropping damage in their wake. The public has finally had enough – as grateful as they are to have their local hero, the good citizens of Los Angeles are wondering what they ever did to deserve this..
