The film has been criticized for distortion of history for dramatic effect, and miscasting in its choices of Paul Newman for the role of General Groves, and Dwight Schultz for the role of Oppenheimer. Noted critic Roger Ebert felt the film lackluster, giving it 1 and a 1/2 stars, and felt that ' The story of the birth of the bomb is one of high drama, but it was largely intellectual drama, as the scientists asked themselves, in conversations and nightmares, what terror they were unleashing on the Earth. "Fat Man and Little Boy" reduces their debates to the childish level of Hollywood stereotyping '.  The film holds a 53% rating on review aggregate Rotten Tomatoes

In 1866 he found himself at odds with the mainstream party over his support for the war with Austria . He was not one of those who formally broke away from the party, but after this his conduct in the Reichstag was increasingly independent, while his contributions were chiefly on matters such as taxation which, within the party, were relatively uncontentious.  Following unification , in 1871  and again in 1874 he was re-elected to the Reichstag , still as a Progressive Party member representing Breslau-West.
