This year's big Arrowverse crossover between SupergirlThe FlashDC's Legends of Tomorrow and Arrow will be more personal than ever. IGN reports that the minds behind The CW's DCTV shows teased romance and other "life events" for the big crossover during the network's panel at the Television Critics Association press tour.

Asked for a tease of the upcoming crossover, CW president Mark Pedowitz said only, "Romance is in the air." Later, The Flash executive producer Greg Berlanti expanded on that, explaining, "Our way of making the show bigger this year was to go even more personal, so it's a big life event for a few different people on the show... There are many life events that happen."

"We're really approaching this big four-part event as two back-to-back two hour movies, and I think when you look at it through that lens, it becomes less important for the Supergirl episode to feel like a Supergirl episode and the Arrow episode to feel like an Arrow episode, which was always our approach in the past," added Arrow executive producer Marc Guggenheim. Accordingly, the crossover will fold all four full episodes into the story.

“Last year was the most successful week in CW history in terms of ratings and everything," Pedowitz said earlier today after announcing the dates and times for this year's crossover. “We felt in this particular case we had Flash on Legends paired, so it was better to make it a two two hour movies -- a miniseries -- we thought this was the best way to go. We had a lot of conversations with producers and marketing people. Next year, we might go back to four nights.”

The 2016 crossover, “Invasion!,” was spread across four nights, beginning with a brief introductory scene at the end of Supergirl‘s fall finale and continuing full force across the network’s other three DC Comics-based dramas, which were then spread across three nights of programming. Last year’s crossover propelled Arrow, The Flash and Supergirl to season-high ratings, and Legends of Tomorrow to a series high.

This year's Arrowverse crossover will begin Monday, November 27, with back-to-back episodes of Supergirl and Arrow, followed Tuesday, November 28, by The Flash and Legends of Tomorrow. The event sees Arrow move from its new Thursday time slot to Monday for one week only.
