Shipp played the Flash on the original 90s live-action and he was cast to play Barry Allen’s father in the more recent CW version.
John Wesely Shipp was present at Dragon Con 2017, where he was asked what he felt about Ezra Miller taking over the role in the DCEU.
Shipp now gets to play his own version of the Flash on the show as Jay Garrick, who in the comics is the very first person to carry the mantle.
Shipp answered perfectly that the Speed Force (the extradimensional source of all speedster’s powers) was big enough for everyone, indicating that he’s perfectly fine sharing the character with a new actor.
