I saw this movie many years ago in TV. It was a classic one, maybe 50s or 60s at most. It was about 3 or 4 people, maybe sailors, who are splitting after ending their service, and are in a bar. They somehow decide to meet again 20 or 25 years later, and write a letter to themselves they put somewhere in the bar.
Then the movie jumps to years later, when they actually get back, each one expecting to be the only one to show up for the meeting, and tell themselves of their lives.
Anyone remembers it?
