Arrow star Stephen Amell promises this year's CW DC crossover will be bigger and better than ever before. And while the Supergirl series was only tangentially connected to last year's alien invasion extravaganza, Amell says Kara and friends will play a much more crucial role in this year's festivities.

As production gets underway on The CW corner of the DC universe -- which currently consists of Arrow, The Flash, Supergirl, Legends of Tomorrow, and, maybe someday, the new series Black Lightning -- and the network rolls out its plans for San Diego Comic-Con later this month, Amell has been commenting not only on what will become of Oliver Queen's world as Arrow moves into season 6, but how all four shows will connect for their now annual superhero get together.

Amell has long been one of the DC television world's most enthusiastic cheerleaders, and he's once again sharing his insights into what's to come. As reported by Comicbook.com, Amell jokingly acknowledged the expectation that the multi-show crossovers have to keep getting bigger in scale to surpass the previous year's entry.

"I think that the whole idea is that after the success of last year, we tone it down, and not include all the shows and just kind of make it as pedestrian as possible. Or the exact opposite of that!"

Understandably hesitant to talk about specific plot points for the crossover, Amell did confirm that one of the biggest criticisms of last year's event would be corrected this year, as the Supergirl series will play a much more integral role.

"I think the idea this year, from what I understand is, last year they said four-night crossover but in a lot of ways, Supergirl was just kind of a lead in to The Flash, so I think this year they really want to get everyone involved. It's not going to be a four-night, well I guess four-night, but Legends and Flash are on the same night. I think they want to get everyone involved in every show. I like having the anchor, we have the anchor this year, Thursday night."

In a season where a few of The CW shows -- particularly The Flash -- were suffering through well publicized creative slumps, the "Invasion!" crossover was a breath of fresh air, sidestepping the personal angst that often hamstrings the heroes of The CW and reminding people why they tune into these superhero hijinks on a weekly basis. The sequel has a lot to live up to, but an increased presence for Supergirl and her supporting cast is a promising early sign.

Arrow season 6 premieres October 12, 2017 on The CW.
