I've seen it a few times. The first time I saw it was in the late 1960's when it was shown on American network television. I remember the greenhouse scene when Jack Lemon's character went berserk looking for the bottle he hid, but couldn't find. I was just a child and I didn't quite understand alcoholism. I distinctly remember my parents explaining alcoholism. Interestingly it was directed by Blake Edwards who is better known for his comedies.
It's about time I watch it again.
