Missing the lead actor in your movie four months before its release? No problem! As was evidently thought by director Paul King and the makers of the upcoming children's adaptation, Paddington. A new trailer has been released for the live action movie, which is based on Michael Bond's Paddington Bear creation, whilst neatly side-stepping the absence of a voice for the titular brown bear.

Colin Firth had been cast as the voice of Paddington - the only animated character in the movie - but stepped away from the role after it was decided that his tones didn't fit theanimation. "It's been bittersweet to see this delightful creature take shape and come to the sad realisation that he simply doesn't have my voice," the actor explained last month.

"We love the voice and we love the bear, but as our young bear came into being we agreed that the two didn't seem to fit. So, with somewhat heavy hearts we decided to part ways," concurred the director.

The action does all the talking in the new trailer which shows the inquisitive Paddington exploring the Browns' bathroom but having to trouble getting to grips with everyday objects like toothpaste, mouthwash, toilets and showers. His hapless hijinks flood the bathroom and send the bear on a perilous log flume down the stairs in a bathtub as the Browns watch on aghast.

The film will follow the classic tale of the conscientious little bear who arrives in London from Peru feeling frightened and alone at Paddington Station. Luckily, the kind Brown family notice Paddington with his "Please look after this bear" tag and take him in.
