I saw about the first 20 minutes of this movie years ago. It looked amusing and I want to see how it plays out.
The story: two strangers, Paris: an older American man and a beautiful younger girl. They both board a bus? (train, definitely public transport). The police? board the bus and check for tickets. The woman did not buy a ticker. On impulse the man gives the woman his ticket and then the police speak to him. After this he spends all his time searching for her on buses.
That is when I stopped watching. I have a feeling the man was an author.
If anyone knows this movie I would enjoy watching it. Thanks.
