{font:Verdana, Arial, sans-serif}{size:12.727272033691406px}I want to know the title for a classic movie. I'll try to make a good description of what I recall. First of all it's a colour movie. I believe it's from the beginning of coulour movies. It was filmed only in studios, and the action takes part in Italy (but i don't know if they're english or italian speaking actors) from what I remember, I believe in 17th - 18th century. The story is about some kind of revolution which has as icon an anonymus poet who writes small poems ironizing the politicians. He is searched for and wanted for execution. I remember a scene where the main character rests on the bank of the river that passes through the city. It's not much, I know, but I really enjoyed this movie and I would really appreciate anyone's help. {font}
