LOOK: "Supergirl" & "The Flash" Join Forces in New Behind-the-Scenes Photo

"The Flash" star Grant Gustin offered a little preview of his trip to "Supergirl's" world with a new photo on his Instagram. The snapshot features both Gustin and Melissa Benoist standing side-by-side in costume.

"Those two emblems look pretty good together," he wrote.

Gustin will appear as The Flash on the March 28 episode of "Supergirl." Details on the episode -- including the plot, how exactly Barry Allen finds himself in "Supergirl" territory and the extent of his role in the episode -- have not yet been released.
