Daniel Craig's most treasured possession is his "penis".

The 'Girl with the Dragon Tattoo' actor - who is married to Rachel Weisz - explained along with maintaining a good level of health, his manhood is the most important thing to him.

Asked what his most treasured possession is by Vanity Fair magazine, he replied: "Apart from my penis and my health?"

In addition to having a particular fondness for his genitalia, the 43-year-old star also revealed he has an unusual quirk on his body.
