"The Flash" Hits 100: Our 13 Favorite Behind The Scenes Moments From The Cast!

Written by Brooke Sharland. Published: December 06 2018


CW’s “The Flash” aired its 100th episode this week -- in Season 5, Episode 8, “What’s Past is Prologue” (which I will NOT spoil, because you NEED to watch it yourself). This is such a milestone! The show has been going on for 5 wonderful seasons now, each of which remain fresh with exciting storylines and dynamic characters.




To celebrate reaching 100 episodes, we’ve compiled a list of all our favorite behind the scenes moments from the cast this year!

13. And finally, when the whole cast and crew celebrated 100 episodes together!



Next up for “The Flash” is the highly-anticipated CW Arrowverse crossover, “Elseworlds”. The 3-night event will begin Sunday, December 9, at 8pm with “The Flash” and continue Monday night at 8pm with “Arrow” and conclude Tuesday night at 8pm with “Supergirl”. TUNE IN. If it’s anything like the previous crossover events, it’s bound to be amazing and will totally keep you on the edge of your seat for 3 days straight.




Congrats to Team Flash for 100 amazing episodes. Here’s to the fastest man alive, his amazing team, and 100 more episodes! Cheers!!!
