Harry Potter star Sir Michael Gambon will be lending his voice to a new E4 hidden camera series Bad Robots.

The award-winning thespian, who famously played Albus Dumbledore, will voice a vengeful robot in a six-part prank series which will see a range of machines – from argumentative vending machines to abusive electronic road signs – create infuriating situations for their human users.

Fictional company Tezcorp Industries is behind the technological revolt with Sir Michael Gambon’s eponymous Bad Robot leading the mission to create chaos.

The first episode in the series will see student union member Barney lose his cool when posting a fragile wedding package; a member of the public being offered the opportunity to get a dodgy passport photo printed on a shower curtain, and unfortunate drivers battling with an automated parking ticket machine…

Bad Robots will be coming to E4 in November
