CBS' Supergirl continues to battle DC villains while The CW's The Flash is on break a little while longer, but both heroes are about to collide in an anticipated crossover event later this month. We've seen some behind-the-scenes images of Supergirl star Melissa Benoist and The Flash hero Grant Gustin shooting the upcoming special, but today marks the first official footage from the March 28th episode. And it's not much.

Basically this is a reminder that the crossover is happening. And while it features a couple brief looks at Gustin and Benoist, there doesn't seem to be much here to chew on. I'll expect to see a little more once The Flash returns on March 22nd, since his next appearance following "Trajectory" will be on a different network. The good news is that the crossover is happening; the great news is that we'll get back-to-back nights with The Flash!

Watch the super-brief teaser of CBS's The Flash / Supergirl crossover below:
