While filming this movie, Michael Sheen was asked by Ron Howard if he could record a quick moment of dialogue for Frost/Nixon where Frost is suppose to introduce who he's interviewing the next night.
Sheen, covered in fake blood and arrows sticking out from the day's filming, went to his trailer and recorded the dialogue. He asked someone to take a picture of him doing it and sent it to Ron Howard, who had it framed and displayed.
