Two young people, American Jesse (Ethan Hawke) and French Céline (Julie Delpy) meet on the Budapest - Paris train. They start talking and quickly develop a connection. As they approach Vienna, where Jesse is flying out from the next day, he persuades Céline to spend a day with him in the city, and catch the train to Paris the next day. She agrees, and the two of them spend a magical 24 hours walking around the beautiful city of Vienna, talking about their lives, gradually revealing more of themselves, and falling in love. But as the hours before sunrise slip away, the moment when they will have to say goodbye edges inexorably closer... This is one of my absolute favourite films, it's beautiful, romantic, realistic and humorous all at the same time. The direction and the central performances are outstanding, the story perfectly constructed and the dialogue is both engaging and has a beautiful natural flow. This film is a rare gem to be cherished and watched again and again.
