"Luck had nothing to do with it. I tipped the steward $5 to seat you here."
During Cary Grant and Eva Marie Saint’s conversation in the dining car, the script had her say, “I never make love on an empty stomach.”
This was considered too saucy for a respectable movie, and was re-dubbed to “I never discuss love on an empty stomach.”
If you watch her mouth closely, what she actually said was, “I never make love on an empty stomach.”
