'The Flash': Watch The First Trailer Real Quick

...and then slowly, a bunch more times.

As if the insane "Arrow" season finale wasn't enough, it also gave us our first trailer for "The Flash," the superhero spin-off that will hit The CW this Fall. And now we're so excited, we're running around in circles almost as fast as the scarlet speedster himself.

What's best about the brief look is that it pretty clearly underlines the differences between Oliver Queen (Stephen Amell) and Barry Allen (Grant Gustin). The two shows will clearly occupy the same world, but their tones — and leading men — couldn't be more different.

"The Flash," based on the classic, super-fast DC Comic book character previously came to TV for one season in 1990, starring John Wesley Shipp as Barry Allen, the fastest man alive. Though the 2014 take is unconnected to the original, Shipp will guest star in some unknown capacity.

Instead, the new series spins off from Grant Gustin's appearance on two episodes of "Arrow," following his adventures as he learns to use his powers and solves crimes as a forensic scientist for the Central City Police Department.

The show also stars Jesse L. Martin, Danielle Panabaker, Candice Patton, Carlos Valdes and Tom Cavanagh. It's produced by Greg Berlanti, Andrew Kreisberg and Geoff Johns.
