The Flash isn’t shy about going full-on bananas with its DC villains but did you know Barry Allen’s red suit was painstakingly designed to be as realistic as possible? Or that actors have to stay completely still to get those Flash-y hyperspeed effects? These are just some of the Flash facts racing at you in the fifth episode of ‘You Think You Know TV?,’ which goes under the mask of The CW’s scarlet speedster!

Much as Arrow drew inspiration from some of its CW predecessors, The Flash initially began as a planted spinoff of the emerald archer, before CW brass were impressed enough for a full-fledged Flash pilot. Not only that, but The Flash owes quite a bit to the original 1990 CBS series, including John Wesley Shipp as Barry Allen’s father, Mark Hamill reprising his Trickster role (again!), and several other notable series alum.

For good measure, did you know that Central City bears a striking resemblance to Portland, or that several Flash episodes have blink-and-you’ll-miss-it references to The Big Bang Theory?
