First off, we have J. Edgar a movie directed by famed director Clint Eastwood (Million Dollar Baby and Gran Torino) with actor Leonardo DiCaprio (Inception and Titanic). It tells the story of the first director of the FBI, J. Edgar Hoover. It will definitely be one to watch.
Then there's Breaking Dawn, the first installment in a long awaited conclusion to Stephanie Meyers epic series Twilight. It is one that fans have been awaiting for years!
There's also Steven Speilberg's two movies: War Horse and The Adventures of Tintin. The first is a story of World War II and a boy's horse (adapted from the Tony award winning play which was adapted from the novel) and then the other is based on the famous graphic novels by Georges Remi and it uses motion captures. Both arrive on Christmas.
