Brett Ratner's RatPac Entertainment is reportedly developing a film based on Winnipeg the Bear, the ursine orphan that became the inspiration for Winnie the Pooh and, later, Winnie the Pooh letterman jackets. The story will be drawn from Lindsay Mattick and Sophie Blackall's upcoming picture book Finding Winnie, that being based on the true story of Lt. Harry Colebourn and the bear cub he brought from Canada to London during the first World War. Nicknamed Winnie, the bear ended up being donated to the London Zoo. There, it lead A. A. Milne's son Christopher Robin to change his teddy bear's name to Winnie the Pooh, thus becoming the inspiration for Milne's beloved character. The tale has already been adapted into the 2004 TV movie A Bear Named Winnie, which starred Michael Fassbender as Coleburn. Like Winnie, that Fassbender would go on to inspire the beloved Michael Fassbender character we now enjoy today.
