It’s little wonder Mark Hamill has played the Joker for over 20 years as clearly having a laugh is hardwired into his DNA, and that mischievous streak was on full display last weekend at SDCC 2018 as he went undercover in a variety of disguises as he walked the convention floor.

First,  he came dressed in Brooklyn Nine-Nine gear.

Then he was a First Order Stormtrooper.

Now we need to get Mark walking the halls at a UK convention. You ready for that MIster Hamill?
