Surprisingly, none of the eight Arrowverse actors confirmed for Superman & Lois. It appears that Superman & Lois is the only Arrowverse show that won’t get representation when Grant Gustin’s Barry Allen and Team Flash team up with their fellow DC heroes.
It was announced a while back that in contrast to the Arrowverse’s traditional, wide-scale crossover approach, The CW will be delivering five, significantly smaller crossover episodes at the beginning of The Flash season 8. Just recently, it was revealed that the event, titled “Armageddon”, will involve a battle against an alien threat. Over the course of the five-part story, Barry and Team Flash will cross paths with various Arrowverse characters from outside The Flash, including Ryan Choi (Osric Chau), Atom (Brandon Routh), Black Lightning (Cress Williams), Batwoman (Javicia Leslie), Mia Queen (Katherine McNamara), Damien Darhk (Neal McDonough), and Sentinel (Chyler Leigh).
Noticeably missing from “Armageddon” are characters from Superman & Lois like Superman (Tyler Hoechlin), Lois (Elizabeth Tulloch), or Steel (Wolé Parks) would have been an excellent opportunity for The Flash to build hype for the event. Plus, their experiences with alien adversaries would have made them good fits. As for why it’s not going in that direction, the answer could be related primarily to actor availability and scheduling issues.
It’s worth noting that out of all the Arrowverse actors confirmed to make appearances, only one – Superman & Lois season 2 is set to begin in September.
Unfortunately, not involving Superman & Lois is a continuation of an issue that viewers have had with the shoe ever since it kicked off in February. Though it takes place on Earth-Prime with all the other shows, it’s always felt disconnected from the rest of the Arrowverse. Talk about the Crisis and John Diggle’s cameo were among the rare moments where Superman & Lois reminded audiences that it shares the same world as Barry, Kara, and all the other heroes. One of the benefits of “Crisis” was that its ending enabled more cohesion to exist between the shows, but the Arrowverse doesn’t often take advantage of that, or at least not with Superman. The character or any of his allies popping up in The Flash’s “Armageddon” event would have been a step toward properly demonstrating the connection between Superman & Lois and the wider Arrowverse.
