"There was another incident that took place prior to the shooting of Notorious [in 1944]. Ben Hecht and I went over to the California Institute of Technology at Pasadena to meet Dr. Millikan, at that time one of the leading scientists in America. We were shown into his office, and there in a corner was a bust of Einstein. Very impressive. The first question we asked him was: 'Dr. Millikan, how large would an atom bomb be?' He looked at us and said, 'You want to have yourselves arrested and hae me arrested as well?' Then he spent an hour telling us how impossible our idea was, and he concluded that if only they could harness hydrogen, then that would be something. He thought he had succeeded in convincing us that we were barking up the wrong tree, but I learned later that afterward the FBI had me under surveillance for three months."
