The grand DCTV crossover is upon us, and the Heroes Vs. Aliens action is set to continue all week across all four of the CW's superhero shows. If you can't wait for the next installment in tonight's episode of "The Flash," then don't despair. The CW has got you covered with a special behind-the-scenes mini featurette focusing on the event.RELATED: DC’s TV Heroes Unite in First Promo for CW Crossover EventThe featurette's biggest highlight is undoubtedly the scene where Supergirl shows everyone exactly what it is that makes her so super, but the joyous enthusiasm of the cast and crew talking about finally getting to play together in their big TV sandbox is pretty infectious too.

The 4-night crossover will pit the the Heroes of "Supergirl," "The Flash," "Arrow" and "Legends of Tomorrow" against a group of aliens called the Dominators. The Dominators will exercise mind-control powers over the team of heroes, which means they will likely fight each other at some point before the storyline concludes in “DC’s Legends of Tomorrow” on December 1.

Starring Melissa Benoist as the Girl of Steel, “Supergirl” airs Mondays at 8 pm ET/PT on The CW. The network is also home to Grant Gustin as the Scarlet Speedster in “The Flash,” airing Tuesdays at 8 pm ET/PT, Stephen Amell as the Emerald Archer in “Arrow,” airing Wednesdays at 8 pm ET/PT and Arthur Darvill, Brandon Routh and Caity Lotz in “DC’s Legends of Tomorrow,” airing Thursdays at 8 pm ET/PT.
