The actor infamously attends the Nymphomaniac Volume I premiere with an interesting accessory: a brown paper bag over his head. "I am not famous anymore," his bag reads.

Sending a message! The Amazing Spider-Man stars cover their faces and leave photographers with a powerful statement: "Good morning! We were eating and saw a group of guys with cameras outside. And so we thought, let's try this again. We don't need the attention, but these wonderful organizations do," Emma's card read, with an arrow pointing to her former boyfriend's sign.
