Ten minutes into Will Smith’s latest, Hancock, you can’t help but feel that you’re getting exactly what the latest trailer promised you. There’s a big car chase, there’s lots of gunfire, and in the midst of it is Will Smith as Hancock, lying on a park bench, nursing a bottle and a mighty-looking hangover. Thing is, Hancock has super powers, even if he’s reluctant to use them. So cue one superhero rescue sequence later, replete with $9m of damage done in the process, and the scene is set for the mix of comedy and action that you’re probably ready to sign up for.
