"The Flash" is a go at The CW, and Wednesday night's airing of the "Arrow" season finale included the initial teaser trailer for the spinoff series -- which features the first look at Barry Allen (Grant Gustin) in motion as The Flash for the first time, outrunning one of fellow DC Comics superhero Oliver Queen/the Arrow (Stephen Amell's arrows.

Gustin first appeared as a non-powered Barry Allen in two "Arrow" episodes last December, and this clips clearly reminds viewers that the two shows are set in the same world. The CW's upfront presentation is scheduled for Thursday, which should include time slot information for both "The Flash" and the third season of "Arrow," plus fellow DC-based series "iZombie."
