British actor and James Bond star Ben Whishaw has been cast as the voice of Paddington Bear in the upcoming CGI/live-action feature Paddington , replacing Oscar-winner Colin Firth . “Delighted to announce that Ben Whishaw will be the voice of Paddington,” producer StudioCanal said in a tweet sent Friday. But I was persuaded to go, slightly grudgingly,” the 33-year old said, adding that growing up, he had had no relationship with the beloved children’s character created by English author Michael Bond .
