Hollywood A-lister Kevin Costner has joined the celebrity team backing the All Blacks after being snapped proudly wearing an All Blacks jersey with Richie McCaw's surname and playing number on it.

Two images of the 60-year-old acting legend wearing the replica were posted to Instagram and Twitter by a friend with the message: "TinCup wishing @dancarter #RichieMcCaw and the boys the best of luck this weekend from sunny California. Maybe he can play Shag in the @allblacks movie."
