For this week's Tuesday trailer, we have Disney's new live action look at the adventures of Winnie the Pooh. It has been more than fifty year's since the first Disney animated short based on A. A. Milne's Winnie-the-Pooh stories first hit theatres. Christopher Robin takes these characters in the live action realm, as Pooh, Piglet, Tigger and the others try to assist the now adult Christopher Robin. Jim Cummings, who has voiced Pooh for the last three decades, returns for this new adventure, accompanied by Ewan McGregor and Hayley Atwell. Christopher Robin is sure to be a very heartwarming film when it opens on August 3.
