Wil Wheaton Appears in Crisis on Infinite Earths

Geek superstar Wil Wheaton (Stand By Me, Star Trek: The Next Generation) makes a hard-to-miss appearance in the latest trailer for The CW's "Crisis on Infinite Earths," playing a doomsayer with a "The End is Nigh" placard who...well...he's more or less right. Even with the high stakes of the storyline, this is far and away the most fatalistic trailer for "Crisis on Infinite Earths" yet, with Oliver Queen (Stephen Amell), Barry Allen (Grant Gustin), and several more characters either outright saying or coming very close to saying that they are going to sacrifice themselves. You can check it out above.

Wheaton's character you can see in the image below. It appears as though he is going to be on Earth-38 (where Superman and Supergirl live) -- a world that a lot of fans already assume really is doomed.

In that way, the idea of having a guy with a placard declaring as much almost feels like a wink and a nod to the BBC version of The Hitch-Hiker's Guide to the Galaxy, in which that image was played for humor...but in the case of "Crisis," the humor would be a lot darker.

"Crisis on Infinite Earths" has loomed over the Arrowverse for years. The series premiere of The Flash featured an allusion to the hero disappearing amid red skies in the year 2024. During the original comics event, red skies were a sign of doom to come to a world during the Crisis. At the end of last season, a couple of things happened: The Monitor (LaMonica Garrett), who had appeared in "Elseworlds," reappeared and revealed that Oliver Queen was destined to die in the Crisis...and the future newspaper at STAR Labs rolled back the expected date of the Crisis from 2024 to 2019.

In the comics, Crisis on Infinite Earths centered on a battle between the combined superheroes (and even some villains) of the DC multiverse and an immortal, cosmic threat known as the Anti-Monitor. Like The Monitor, the Anti-Monitor will be played by LaMonica Garrett in the Arrowverse. As the Anti-Monitor destroys realities, he replaces their positive matter energy with antimatter, growing his own power and sphere of influence. He was eventually stopped by the sacrifices of several heroes, including The Flash and Supergirl, as well as the merging of multiple universes to save reality by becoming a single, unified timeline. Fans have long wondered whether the events of "Crisis on Infinite Earths" might bring Supergirl and even Black Lightning to Earth-1, where the rest of the series take place. The crossover will also feature guest appearances by Tom Welling as Clark Kent, Erica Durance as Lois Lane, John Wesley Shipp as the Flash of Earth-90, Johnathon Schaech as Jonah Hex, Kevin Conroy as Bruce Wayne, and Ashley Scott as The Huntress.

"Crisis on Infinite Earths" kicks off on Sunday, December 8 on Supergirl, runs through a Monday episode of Batwoman and that Tuesday's episode of The Flash. That will be the midseason cliffhanger, as the shows go on hiatus for the holidays and return on January 14 to finish out the event with the midseason premiere of Arrow and a "special episode" of DC's Legends of Tomorrow, which launches as a midseason series this year and so will not have an episode on the air before the Crisis.
