So is Cillian Murphy going to spend the entire film looking haunted and forlorn about being the father of the A-bomb? Because I don’t want to go on a guilt trip with this guy. I really don’t. If it hadn’t been for the Hiroshima and Nagasaki bombs that led to Japan’s surrender, my Marine lieutenant dad would’ve been ordered to take part in a huge land invasion of Japan. The odds of survival would have been quite low. Tens of thousands of U.S. servicemen would have died. War is hell, war is horrific…I don’t want to watch a movie about J. Robert Oppenheimer feeling bad and gloomy. I really don’t. He can go through the gloom later in life.
