This Friday, July 3rd, Tom Hardy and other actors such as Terry Jones, Charlotte Riley, Stephen Fry, Graham Norton, will be wearing an "eye-catching" item of clothing to bring awareness (?) to colon cancer. Colon cancer is the U.K.'s second biggest deadly cancer even though it is curable. They invite others to join them.

hopefully it's his birthday suit.
