Can't wait for a "Supergirl" episode where The Flash will appear? Grant Gustin knew it, so he offered a glimpse of the crossover while filming of the episode is still underway. He took to Instagram on Wednesday, February 10 to share a picture of him and Melissa Benoist on the set of the CBS series.
In the said photo, both Gustin and Benoist are in their superhero costumes and look beaming while standing on a vast green field. "Those two emblems look pretty good together... @melissabenoist," so he captioned it.
Clearly excited about his guest appearance on the CBS series, the "Flash" star posted other images documenting his day at work shooting the "Supergirl" episode. "Hey Flash producers... I've already got a fancier chair on Supergirl than I've got on Flash. Just saying...," he jokingly wrote along with a picture of his empty chair.
"Supergirl" / "The Flash" crossover will air March 28 on CBS. The two superheroes' team-up was already teased in the latest episode of "The Flash" as Barry saw a glimpse of Kara flying in the multiverse.
