Marvel's Big Hero 6 adds another director

Disney and Marvel's Big Hero 6 has added a new director to its production team, with Bolt 's Chris Williams joining existing helmer Don Hall.

The film will follow young Hiro Hamada, a teenage robotics whizz, and his best friend Baymax, a distinctly cuddly-looking robot.

When Hiro gives Baymax a few badass upgrades, the duo head off to join a posse of wannabe crime-fighters, who uncover a fiendish underworld plot that threatens their city's safety.

The film has also released a new image online, showing off the San Fransokyo (the fictional hybrid of San Francisco and Tokyo where the film is set) skyline in all its glory.

Big Hero 6
is currently slated for a US release on 7 November 2014, with a UK date still to be confirmed.
