If you love history this is for you. It taught me more about US history.

I enjoyed the way the director switched from black and white to colour as a way of differentiating between transcript based re-enactments and story based portions of the film. Great special effects and Oscar worthy performances throughout the film. 3 hours flew by. It is a must see!

A great story telling about the creation of the Atomic bomb and background of the inventor.The cast of actors were top notch with Cillian Murphy and Robert Downey Jr. giving Oscar nominated performances.

Very powerful and very thought provoking.
