A great cast and very entertaining film!

Actually 4.5 stars. This movie was very entertaining with a great storyline. It was "slow" for the back story, but that didn't matter much since there was so much action. I recommend this movie and will probably watch again since my wife wasn't present.

Good Compelling Movie. Bio Pics typically can be hit or miss this was shot well and well acted. My only gripe is it was about 40 minutes too long

The movie was an excellent history lesson about the creation of the atomic bomb and the creator, Oppenheimer. If you are not aware of the story, it is a very educational experience with not only the public perception but inside accounts of what was going on behind closed doors.
