However, I saw the script itself as being the problem, not the actors - Paul Newman, Dwight Schultz, John Cusack, Laura Dern - all were excellent insofar as the script allowed them to be. I will agree the history was fascinating, and that the acting appeared not to be strong. One reviewer who said they had watched this for chemistry class commented the history was good but the acting wasn't strong. Out of five stars, I would give 'Fat Man and Little Boy' three.
