Superman: Superman: The Movie part 6
Superman reaches its crisis point as Lex Luthor explains his scheme to Superman and Superman stands there and looks shocked. Keep in mind, Superman knows that the army and navy are testing two nuclear missiles that day, and he also knows that Lois is “out west checking into a big land sale,” and yet, as Luthor patiently explains his plan to him, he still puts nothing together on his own and does not act even after Luthor is done with his presentation. Luthor was banking on Superman’s goodness, but he needn’t have bothered – he could have banked on Superman’s total lack of deductive reasoning.
