New Hancock Sneak Peek

More footage from Will Smith's next

A new promo for Hancock premiered during US TV show American Idol last night, and you can now watch it below.

Hancock stars Will Smith as a superhero who loses favour with the public thanks to his surly, booze-sodden ways. He then employs a PR man (Jason Bateman) to spruce up his image, but that working relationship leads to further complications.

Is it possible for a Will Smith movie to be a sleeper hit? He's a man of enormous opening weekends, but this film is operating under a different level of anticipation than most blockbusters this year. Everything shown from it so far looks like terrific fun and, in a summer where many films will have to be masterpieces to satisfy expectant fans, a movie that's simply silly, original fun could do very well.
