This is awesome. Heroic Hollywood has the poster and episode description for the March 28 crossover episode of Supergirl featuring Grant Gustin as The Flash.

I love the way the poster echoes the classic cover of the first Superman/Flash race back in Superman #199 (via comics.org):
I cannot wait for this crossover. It is going to be super! Interesting, though, that Flash comes from an alternate universe. I suppose it has to be that way because both shows are on different stations. One thing is sure, if there can be a Supergirl/Flash crossover, there will be a Flash/Supergirl crossover. Maybe even a “ménage à trois” crossover with all teams, eventually.
I don’t think it’s just the fact that they’re on different networks. The shows have different backgrounds to their worlds:
On “Supergirl,” Superman has been operating in public for something like 15 years. That’s hard to reconcile with the sudden appearance of metahumans two years ago in the “Flash”/”Arrow” verse.
Additionally, Kara makes her debut as the world’s second public super-hero at the beginning of the show — at a time when Flash has been around for a year and Team Arrow (admittedly not super-powered) for several. It’s a little different if she’s the first new superhero in 15 years vs. just the latest of many.
Looks very cool! I haven’t watched any episodes of Supergirl yet, but will be watching this.
