No offense to Steve Martin and Goldie Hawn, but this movie should not have been remade. It's not fair to Martin-Hawn that Lemmon-Dennis hit their version out of the park. Any remake would suffer.
Jack Lemmon as George Kellerman is a lesson to us on how not to act in any place out of your natural environment.
He is fantastic with his taking down names, numbers, badges, offices, titles, and whatever else he can remember (expecting a cabdriver to mail you change?). And in typical New York fashion, everybody reacts with a "Yeah? So what?" attitude.
Rule #1 when you're an out-of-towner visiting a "big" city: Don't draw any more attention to yourself than you already have. This goes double if you're not in your own country.
You just want to go up to him and say "forget a life in this city, you can't even handle a night in this city!" Rule #2 is more basic than Rule #1 (this goes even for when you're at home). Just behave yourself.
