The Last Duel is an intense drama, but Matt Damon‘s hair for the middle ages-set film is downright hilarious. The actor, 49, is sporting a shaggy, curly mullet — much different from his usually cropped style. Another major difference? Matt is rocking a grey-ish beard on just his chin and neck. It’s a… look. The Oscar-winner’s costume was revealed in new photos taken at Cahir Castle in Cashel, County Tipperary, Ireland, where he was spotted strolling with co-star Jodie Comer.
