Cisco is the most obvious person to go to for movie quips and quotes, but I’d love to hear a Harry Potter reference coming from someone more random.
Like one of the Central City PD extras who also happens to be played by Daniel Radcliffe.
I realize that’s a stretch.
Considering just how interestingly The Flash has used both John Wesley Shipp and Mark Hamill from the 1990s Flash series, I think viewers are well aware that this creative team has zero hesitation giving a wink and a nod to anyone who gets their references.
