SDCC 2014 - The Flash in New Promo Clip

A new promo for The CW's "The Flash" TV series pulls double duty, promoting the Scarlet Speedster's fall debut while teasing the addition of Brandon Routh's Ray Palmer to the cast of "Arrow."

The 30-second teaser not only showcases Grant Gustin's character's speed -- he tops out at 760 mph -- it prominently features a billboard for Palmer Technologies which declares 'Bigger isn't always Better' in the signature blue and red of DC Comics hero, the Atom.

"The Flash" series premiere, which will be screened at Comic-Con, airs Tuesday, Oct. 7, on The CW.
