CW's ‘Flash’ Takes on ‘Arrow’ in Epic Crossover Event Trailer (Video)

It had to happen, and it was bound to be epic. In the trailer for the first full crossover between The CW's “Arrow” and “The Flash,” it looks like fans are in for a superhero odd couple. Grant Gustin's light-hearted take on the fastest man alive is a far cry from Stephen Amell's grim and gritty Arrow, but that's a lot of what makes the crossover look like so much fun.

Happening across two nights on both shows, the crossover promises team-ups and a superhero brawl between the two DC Comics heroes.

“Barry has super-powers,” Danielle Panabaker‘s Dr. Snow says at one point in comparing the two heroes. “Oliver has a bow-and-arrow.”

But don't count Mr. Queen out just yet. Like Batman, he knows to use his smarts when faced with super-powered foes … or allies. Plus, now in his third season on the air, the Arrow has been at this hero business a lot longer than the Flash.

The crossover begins Tuesday, Dec. 2 on The CW. Watch the trailer.

“The Flash” airs Tuesdays at 8 p.m. ET while “Arrow” airs Wednesdays at 8 p.m. ET on The CW.
