Arrowverse Role: The Flash as Henry Allen/Jay Garrick
Other DC Universe Roles: The Flash (1990) as Barry Allen/The Flash, Batman: The Brave and the Bold as Professor Zoom
1990s’ The Flash TV show is pretty goofy by modern superhero television standards, but John Wesley Shipp still acquits himself very well as the titular hero. The first live-action portrayal of Barry Allen, Shipp felt like he stepped right out of the comic books.
Despite a solid career in the decades since, then, Shipp will forever be synonymous with the Scarlet Speedster. In a fun twist, he turned up in an episode of Batman: The Brave and the Bold as The Flash’s enemy Professor Zoom. More notably, though, he featured in the recurring – and symbolically-heavy – role as Barry’s father on 2014’s The Flash for its first two seasons. For season 3, he got to don The Flash mantle again – this time as Earth-3’s resident speedster, Jay Garrick.
