The Flash seems to be getting decent ratings on its own (and is more universally loved than Arrow, at least to this outsider), so it doesn't really need to do a crossover episode at this point, even though such a thing has most certainly been in the cards since the show's inception.
I keep meaning to carve aside some time to dig into both of these series, but they keep eluding me. Maybe if I check out the crossover episode that will be a decent place to dive in to get a flavor of both? Regardless, for existing fans of the shows these images of Grant Gustin and Stephen Amell spending more time together than usual prove to be a nice afternoon surprise. Part one of the Flash vs. Arrow crossover event is technically an episode of The Flash and airs on the CW on December 2nd at 8/9PM ET. Hit the jump to check out the images.
Here's the synopsis for Flash vs. Arrow:
Barry (Grant Gustin) is thrilled when Oliver (guest star Stephen Amell), Felicity (guest star Emily Bett Rickards) and Diggle (guest star David Ramsey) come to Central City to investigate a case involving a deadly boomerang. Excited about teaming up with his friend, Barry asks Oliver if he’d like to help him stop Ray Bivolo (guest star Paul Anthony), the meta-human Barry is currently tracking. Bivolo causes people to lose control of their emotions and has been using that skill to rob banks. Unfortunately, the superhero partnership doesn’t go as smoothly as Barry expected. When Oliver tells Barry he still has a lot to learn, Barry sets out to prove him wrong by attempting to stop Bivolo alone. However, when Bivolo infects Barry and sets him on a rage rampage, everyone is in danger, and the only one who can stop him is the Arrow. Meanwhile, Iris (Candice Patton) is furious when Eddie (Rick Cosnett) tries to get a task force to stop The Flash, Joe and Dr. Wells (Tom Cavanagh) agree the Arrow is a bad influence on Barry, and Caitlin and Cisco deal with a new team in S.T.A.R. Labs.
