With the first episode of the CW’s Crisis on Infinite Earths debuting tomorrow night, excitement is building among DC comics fans for what is sure to be a ground-breaking TV superhero event.  Featuring episodes of the live-action series Supergirl, Batwoman, The Flash, Arrow, Black Lightening, and Legends of Tomorrow on The CW, the sixth annual Arrowverse crossover event will span five hours over this month and January, with A two-issue comic also tying in, featuring characters and concepts not able to appear in the live-action episodes.

“Crisis on Infinite Earths”, inspired by the comic of the same name, continues plot lines established in the previous crossover, “Elseworlds”. The five hour arc has the Monitor gathering Green Arrow, the Flash, Supergirl, Batwoman, the Legends, and at least seven other heroes from throughout the multiverse to stop the Anti-Monitor from destroying all reality.

When asked what they were most looking forward to as Crisis on Infinite Earths unfolds, DC fans were more than happy to answer.

“Looking forward to Tom welling, even if he doesn’t get that much screentime that guy still made my childhood memorable.” Ric Grayson states, referring to Smallville’s Clark Kent, set to appear with his onscreen Lois Lane, Erica Durance.

Cameos from DC Comic’s storied movie and TV universes were top of mind for most fans, including Terrance Perry, who is excited to see Kevin Conroy as Kingdom Come Batman/Bruce Wayne.

DC media is famous for including actors from older incarnations of their properties in new versions, and Crisis on Infinite Earths appears to be working overtime to include as many familiar faces as possible. Other than Welling, Durance, and Conroy, Burt Ward, Robin from the 1960s Batman TV series, is on-board, along with Ashley Scott (from the short-lived Birds of Prey) as Huntress, Brec Bassinger as Stargirl,  Jonathan Schaech as Jonah Hex, David Ramsey (currently John Diggle on Arrow) as (maybe) Green Lantern, and John Wesley Shipp as TV’s original Barry Allen/The Flash.

We’ll also be treated an an at least passing reference to Michael Keaton’s Batman.

Perhaps the biggest news is Brandon Routh, who is currently the Atom on DC Legends of Tomorrow, donning the red cape again as Superman, the same version he played in Superman Returns, which was an indirect sequel to director Richard Donner‘s Superman The Movie and Superman II. According to Arrowverse producer Marc Guggenheim, Routh’s portrayal is the closing chapter of the Christopher Reeve era. He’ll be the older, wiser, Kingdom Come Superman.

Many fans are exited for the potential easter eggs and rumored, though not confirmed, characters that may or may not be appearing. Chief among these is Lynda Carter as Wonder Woman and Justin Hartley as Smallville’s Green Arrow. A new rumor is Gerard Christopher, the second actor to portray Superboy in the 1980s syndicated series of the same name, will also cameo. And Julie Newmar‘s name, one of TV’s Catwomen, keeps popping up as well.

Based on last year’s closing moments, we might also see some versions of Hawkman and Hawkgirl and Dr. Fate.

“These five hours should be an easter egg hunter’s dream,” remark fan Thomas Lance. “Look for sight and literary references ranging 80 years of DC comics.”
