Leaving aside questions of historical accuracy, Tome Cruise's Valkyrie was a much better film. This film (Operation Valkyrie)did a poor job in the introduction and fleshing of characters. Despite the name of the film, it was not even explained clearly what Valkyrie was. Valkyrie was also better in describing the events leading to the final assassination attempt, while this film had serious problems in its pacing. For example, just after Stauffenberg's scene at the hospital, in the next scene we altready see him dictating the document about Hitler's death to Tresckow's secretary.
This film was also too simplistic in regard to Stauffenberg's motives. The idea that he came to the conclusion that Hitler had to be removed after after a few German defeats, and after hearing a single woman describing Nazi atrocities was outright silly.
While how the film would end was a foregone conclusion, Valkyrie was still able to generate suspense and grip the viewer's attention until the end. This one seemed to be as exciting or suspenseful as an average episode from the History Channel, but without the latter's usual clarity in exposition.
This movie was slightly better. Tom Cruise talking with an American accent in English was incredibly lame!
id have to say Valkyrie is the better film, as has been mentioned there wasn't enough detail on what operation Valkyrie is,who the main player's where and the worst bit was Stauffenberg speech at the end.
"i hope for peace, where everyone can be free and equal blah blah" is totally at odds with the person Stauffenberg was to all accounts was disillusioned with Hitler's leadership but still opted for a totalitarian state.
I understand why German media portrays Stauffenberg as a hero maybe he is, but don't think of him if he succeeded off being a loving democratic liberal, he wasn't.
