Still a hilariously funny film and one of the classic 'everything that can go wrong, does go wrong' movies.
It's aged really well, and is superior to the 1999 remake (with Steve Martin and Goldie Hawn) in many ways. The photography captures the mood of each scene, and really gets across just how small George and Gwen feel in this towering city. They face far more problems than in the remake too, creating an even greater sense of dispair and farce. Perhaps most important, Jack Lemmon and Sandy Dennis portray genuinely nice people, which I just didn't feel in the remake where Steve Martin's George is much 'angrier'. You watch and while you're laughing, really feel for them at the same time. I found myself willing them along, and if you've had to travel to foreign cities much you'll watch with a real empathy - there but for the grace of God...
