Two men accused of attempting to extort Michael Bay on the Hong Kong set of his latest Transformers movie have pleaded not guilty. The filmmaker claims he was attacked by local shop owners in October (13) after he refused to hand over a payment of $12,900 (£8,600) for the inconvenience caused by the Transformers: Age of Extinction movie shoot. Brothers Mak Chi-shing, 27, and Mak Chi-hang, 28, were arrested and charged with blackmail and assaulting police officers who responded to the incident. The pair appeared in a Hong Kong court to enter not guilty pleas on Tuesday (04Feb14). Bay accused the pair of blocking the road with bricks outside their store and blasting loud music in a bid to halt production on the film after movie workers refused to pay them off. He claims they then hurled an air-conditioning unit at him before turning on local cops.
