Mark Hamill is in epsiode 17 of The Flash and there is a scene in there that will make you laugh

watching this makes me think he would make a great Sith

Mark Hamill was the trickster in the Flash movies (or was it the TV series) in the 90's i think, also the guy who plays the Flash's dad in the current series was the flash from the original 90's series.

Check it out here http://en.wikipedia.org/wiki/The_Flash_(1990_TV_series)

Mark Hamill was also the voice of the Joker in the Batman cartoon in the 90's

Don't forget Firelord Ozai. Lotta parallels to Luke's old foes there.

Don't forget this treat ... actually .. do!

Ozai: "No Aang, I am your father."

Aang: "Yeah, no. You're talking to the wrong guy, firelord."

Ozai: "No Zuko I am your father."

Zuko: "Wha? Well Duh!"

Lol the Guyver. Atleast the anime was decent.
