Mark Hamill is known by many for being Luke Skywalker.

Others recognize him as the Trickster from both Flash tv shows.

And some others recognize him as....

The Joker.

So if he decided to ever be Santa, he's going to have some problems.

The Star Wars kids would be happy to see him.

The Flash Fanatics would avoid him.

The Batman Arkham Fans would hide....

The DC Fans won't look at him....

And the Star Wars DC Fanatic would be running around in circles screaming.
