It looks like Mark Hamill will be returning to The Flash. If you did not know he played a character called the Trickster in the 90’s TV show The Flash. Check out this clip:
There will be some changes in the character, this time he is “an anarchist terrorist serving a life sentence. When a copycat Trickster starts wreaking havoc on the city, The Flash (Grant Gustin) and Det. West (Jesse L. Martin) seek Hamill’s character out for help.” We will have to wait until 2015 to see him on the new Flash.
