For one week only, Arrow will air in a Monday at 9PM timeslot to make this happen, as all four shows will run together in an almost miniseries-like format. The announcement was made by The CW’s Mark Pedowitz this morning at the Television Critics Association press tour.
The four-show crossover begins Monday, November 27 at 8PM with Supergirl. Arrow will follow at 9. The action continues the next night (November 28) with The Flash and DC’s Legends of Tomorrow. At this point, a concept for this year’s crossover has not yet been confirmed.
