Probably not what you were thinking of, but, in 1776 (the stage musical, anyway, not sure about the movie), Benjamin Franklin, commenting on how the Founding Fathers will be thought of in the future, says, "What will they think we were, demigods? We're men, no more, no less, trying to start a new nation against greater odds than a more generous god would have allowed." Other than that, the line's not ringing any bells.
