The Flash is dipping into the past once again and having another actor from the early 90s series reprise their role on the new hit CW series. Having already cast John Wesley Shipp as Henry Allen and soon we'll be seeing Amanda Pays as Dr. Tina McGee the producers decided to call on probably the biggest name from the original run, Mark Hamill.
"Mark Hamill returns in a brand new interpretation of James Jesse (aka The Trickster), a role he originated on the 90's 'Flash' series. In this new iteration, The Trickster is an anarchist terrorist con man serving a life sentence in Iron Heights who helps Barry (Grant Gustin) and Det. West (Jesse L. Martin) to foil the city-wide attacks of a wannabe Trickster eagerly following in the original's deadly footsteps. The episode will reunite him with John Wesley Shipp who went up against him as the original 'Flash' on the CBS version."
Hamill was one of the most memorable characters from the original run. It's said that his portrayal of the Trickster caught the attention of producers of Batman: The Animated Series and led to his voicing the Joker for many years.
