Released in 1995.
Plot line: On his way to Vienna, American Jesse (Ethan Hawke) meets Celine (Julie Delpy), a student returning to Paris. After long conversations forge a surprising connection between them, Jesse convinces Celine to get off the train with him in Vienna. Since his flight to the U.S. departs the next morning and he has no money for lodging, they wander the city together, taking in the experiences of Vienna and each other. As the night progresses, their bond makes separating in the morning a difficult choice.
I recently learned that there was a third movie in this series, so have decided to watch the first two again, and oh man does this one hold up. It is beautifully done, and it makes me rather nostalgic for a time without smart phones and internet cafes. A lovely exploration of how a random encounter can deeply affect you, and the part I loved most is that this movie is an ode to the art of conversation.
You can see the trailer here. If you have yet to see it, this is a movie worth watching.
