If ever you needed proof of just how much of a legend Mark Hamill really is, watch the way he reacts when given a custom-made lightsaber at London’s Star Wars Celebration event.

Hamill is presented with the “Joker Custom Saber” — which comes complete with the Joker’s trademark laugh — by a man from Hampton’s Handcrafted LED Sabers, who tells the Star Wars icon that his customers have chipped in to have it made for him.

Despite how shattered he must be after an intensive three-day convention, Hamill still comes across like an all-round awesome guy who’s genuinely humbled to have such passionate fans.
