2016 saw “The Flash”, “Supergirl”, “Legends of tomorrow,” and “Arrow” come together for a four-night CW series crossover event. The crossover saw the DC heroes banding together to overcome an alien threat.

The first-ever event was met with much anticipation and was received very well by fans, which has meant that this type of crossover event will only continue to happen. The network and showrunners have confirmed that an Arrowverse crossover will occur later this year

Stephen Amell speaks out

Stephen Amell, who plays the Green Arrow in “Arrow,” spoke to Comicbook.com about this year’s upcoming crossover event and what fans can look forward to.

Amell expressed that he knew exactly what was going to happen this year. While not giving any plot details away he did jokingly say that with all of the success of the last crossover they had decided to pull back and not have all of the shows included, before quickly calming everyone down by saying that it would actually be the opposite of that.

Unsurprisingly, Amell was unable to give specific details in terms of what the heroes will face and who will be the main antagonist this year. He did explain that the crossover will expand upon what happened last year. He then went on to explain other subtle changes that will occur this time around. “Supergirl” looks set to have a bigger role.

The “Supergirl” episode only saw a two-minute crossover clip, leading into “The Flash” the next night.

This was one of the negative points raised after the crossover aired, as many were expecting her to have a bigger role, especially since “Supergirl” was the first show in the 4-way crossover.

Four-night to four-way

Changes to the scheduling will mean that it will not technically be a four-night crossover, as both “The Flash” and “Legends of Tomorrow” will be on the same night.

This does not mean they won’t cross over. It just means that will be a four-way rather than four-night.

Arrow” has also had a schedule change with the show moving to a Thursday night, now which means that the conclusion to the crossover will be held on “Arrow” rather than “Legends of Tomorrow.” This will mean a night’s break between the penultimate and last episode of the crossover.

This is something Amell is particularly pleased with, as he expressed his delight at being last.

All of the DC/CW shows are to return in the fall after their summer breaks. “Supergirl” returns on October 9, “The Flash” and “Legends of Tomorrow” return on October 10, and “Arrow” is to return on October 12. The official date of the Arrowverse crossover is still to be announced.
