The Arrowverse’s Crisis on Infinite Earths crossover has officially wrapped. Unlike previous crossovers, Crisis on Infinite Earths not only features heroes from across The CW’s Arrowverse, but also a plethora of celebrity appearances from the wider DC movie and television universe, introducing new versions of iconic DC heroes and revisiting past favorites.

As Crisis: Part 1 began, the voice of the Monitor took us through the creation of the Multiverse. The camera whizzed through different Earths and worlds, showing us that there were more than just 52 Earths in the DC Multiverse. As we flew by each Earth we were met with a surprising amount of cameos.
Robert Wuhl as Alexander Knox
Our first cameo came from actor Robert Wuhl, who you may recognize from Tim Burton’s Batman (1989), in which Wuhl played Alexander Knox. In “Crisis on Infinite Earths: Part 1” Wuhl can be seen reading a newspaper as the skies of his Gotham become red. Knox was a reporter for the Gotham Globe in Batman. And what was the name of his Earth? Earth-89, of course.
You can also hear the Batman theme song playing over this scene!
Alan Ritchson and Curran Walters as Hawk and Robin
Our next cameos were of two cast members from Titans, which just wrapped its second season on DC Universe. First, we saw Alan Ritchson, who plays Hank Hall/Hawk on Titans, then Curran Walters, who plays Jason Todd/Robin. This scene took place in San Francisco on Earth-9.
Seeing these actors came as quite as a surprise because Titans is a currently-airing DC show. This is the first time anyone from the DC Universe has appeared on a CW show. (Also, fun fact, before Ritchson was on Titans he played Aquaman on Smallville.)
Russell Tovey as The Ray
Next, we saw Earth-X. We’ve been to Earth-X before, in the 2017 Arrowverse crossover. This Earth was home to evil versions of our superheroes, including the awkward evil power couple of Oliver Queen and Supergirl. Earth-X is also home to the Freedom Fighters, including The Ray. “Part 1” showed us that after the events of “Crisis on Earth-X,” The Ray is still fighting for truth and freedom. Actor Russell Tovey reprised his role for this unexpected but welcome cameo.
Burt Ward as Dick Grayson
Our next cameo was a fun one. As the camera panned over Earth-66, we were treated to an appearance from Burt Ward. Ward played Dick Grayson/Robin in the 1966 series Batman and its subsequent movies. To make this cameo even sweeter, Ward was walking Ace the Bat-Hound! Ward’s inclusion in this episode is such a sweet tribute to one of the most beloved live-action DC shows on television.
Wil Wheaton as a Doomsday Prophet
As the episode zeroed in on Earth-38, Supergirl’s world, the camera focused in on an apocalyptic doomsday prophet, played by none other than actor Wil Wheaton. If you’ve been in the geek community for any amount of time, you probably recognized him. Wheaton is best known for his roles in the film Stand by Me and the TV series Star Trek: The Next Generation. In recent years he has appeared on The Big Bang Theory and as the voice of Aqualad on Teen Titans.
Griffin Newman as the Trivia Host
He may not be a DC character, but Griffin Newman still has superhero cred thanks to his role as the long-suffering Arthur on Amazon’s live-action reboot of The Tick. He can be seen in “Crisis on Infinite Earths Part 1” as the host presiding over a pub quiz attended by Legends of Tomorrow’s Sara and Ray. (Well spotted, Thribs!)
As we ventured into “Crisis on Infinite Earths Part 2,” we were met with even more familiar faces.
Tom Welling as Clark Kent
Tom Welling’s return to The CW was easily the most anticipated cameo/guest star of this Crossover. We found Welling’s Clark Kent on Kent Farm, right where he should be. Welling previously played Clark Kent/Superman on Smallville for over 10 seasons.
Erica Durance as Lois Lane
Tom Welling was joined by fellow co-star Erica Durance. In “Crisis Part 2” she reprised her role as Lois Lane from Smallville. It was lovely to see her Welling on Kent Farm, happily raising two daughters.
Kevin Conroy as Batman
Kevin Conroy voiced Bruce Wayne/Batman in Batman the Animated Series for four seasons. He went on to voice the Caped Crusader in 13 other animated films. In “Crisis Part 2,” Conroy made his live-action debut as Bruce Wayne/Batman. This version of Batman had been badly damaged, thus his reasoning for wearing an exo-suit.
Wentworth Miller as Leonard Snart
As Sara and co. made their way to a new Waverider on a different Earth, she was met by a “retired” Heat Wave. Heat Wave was writing a romance novel and arguing with his ship’s version of Gideon. This Gideon, however, was not voiced by the same person as the Earth-1 Waverider, but by Leonard Start! That’s right, Wentworth Miller AKA Captain Cold was back in a small but cheeky voice cameo.
Johnathon Schaech as Jonah Hex
Jonah Hex was also back for the Crisis Crossover! Actor Johnathon Schaech has appeared in the Arrowverse previously, on Legends of Tomorrow. In this episode, he was the key to finding the Lazarus Pit. He also happened to get his scar (on his Earth) from Sara Lance herself.
“Crisis on Infinite Earths: Part 3” brought even more guest stars.
Ashley Scott as Huntress
Crisis Part 3 kicked off with a glimpse at another Earth – Earth-203, to be precise – where Huntress (Ashley Scott) was still protecting New Gotham alongside Oracle, as seen in their shortlived WB series Birds of Prey, which aired for one season back in 2002-03. Fun fact – Batwoman’s Alice, Rachel Skarsten, also starred in Birds of Prey as another DC character: Dinah Lance.
Cress Williams as Black Lightning
Jefferson Pierce (Cress Williams) may be the star of his own CW series, but Crisis Part 3 marked Black Lightning’s first appearance in the Arrowverse – a probable precursor to the end of the Crisis, when we’re predicting that his Earth (like Supergirl’s) will likely be merged with the rest of the Arrowverse to facilitate future crossovers.
Tom Ellis as Lucifer Morningstar
A resident of Earth-666 (of course) where his Fox-turned-Netflix series apparently takes place, Lucifer Morningstar (Tom Ellis) seemingly has a history with Earth-1’s John Constantine (one we would LOVE to see explored in some kind of one-shot special, if anyone at Warner Bros. is listening!) that prompted him to give John, Mia, and Diggle a ticket to Purgatory to try and retrieve Oliver’s soul. Unfortunately, that didn’t go completely to plan…
Part 3 snuck another cool cameo into the already enjoyable Lucifer sequence. A billboard on Earth-666 features an advertisement for HBO’s Watchmen series. This doesn’t necessarily confirm Watchmen exists in this live-action multiverse (as it does in DC’s comic multiverse), but it’s a fun reference regardless.
Stephen Lobo as Jim Corrigan/The Spectre
DC fans – and those who watched Matt Ryan’s shortlived Constantine series – will be familiar with the name Jim Corrigan, who was played by Emmett Scanlan in Ryan’s NBC show. But the troubled detective took the form of Stepen Lobo (no relation to the Main Man, we’re guessing) in Crisis Part 3, revealing himself to be The Spectre and setting up Oliver Queen to take his place as the green-hooded antihero.
Osric Chau as Ryan Choi
Supernatural star Osric Chau made his Arrowverse debut as Ryan Choi, another version of The Atom and successor to Ray Palmer, in Crisis on Infinite Earths: Part 3. While this isn’t technically a cameo, since he’ll presumably be appearing in Parts 4 and 5 of the crossover (and maybe even joining the Legends once Brandon Routh leaves the series), it’s still a notable DC character appearance, so we figured we’d include him here.
John Wesley Shipp as Barry Allen of Earth-90
John Wesley Shipp donned his 1990 Flash costume one last time in Crisis Part 3, as Earth-90’s Barry Allen sacrificed his life to stop the Anti-Monitor’s anti-matter cannon so that Earth-1’s Barry could live to run another day. It was an emotional moment, made all the more resonant because the episode utilized a clip from Shipp’s iteration of The Flash, showing Barry with his future wife, Tina McGee, before he died.
Ezra Miller as DCEU Barry Allen
In perhaps the single biggest cameo of the entire crossover, Grant Gustin’s Barry Allen bumps into Ezra Miller’s Barry Allen inside the Speed Force in Part 4, confirming even the DCEU exists as part of the same multiverse. What’s more, it appears the DCEU Barry is inspired by this crossover to take up the Flash name.
Marv Wolfman as Marv Wolfman
The Arrowverse shows often namedrop famous DC Comics creators when it comes to street names and landmarks, but Crisis: Part 5 goes a step further by giving original Crisis on Infinite Earths writer Marv Wolfman a cameo role. Wolfman is the eager fan who approaches Flash and Supergirl for an autograph as the two heroes are coming to terms with the existence of Earth-Prime.
Brec Bassinger as Earth-2 Stargirl
Crisis: Part 5 reveals how exactly the upcoming Stargirl series fits into the larger multiverse. Though Earth-2 was the first to fall in the buildup to Crisis, it’s now been replaced by a new Earth-2 that will serve as the setting for Stargirl. In addition to Brec Bassinger’s Stargirl, we also see her armored stepfather S.T.R.I.P.E. (Luke Wilson), Doctor Mid-Nite (Henry Thomas) and Hourman (Lou Ferrigno, Jr.).
Earth-12 Green Lanterns
Part 5 forges a bond with another DC movie universe, revealing Earth-12 to be the setting of 2011’s Green Lantern. We don’t actually see actors like Ryan Reynolds and Mark Strong reprise their roles, but it’s nice to know the the multiverse still has some Lanterns.
Following up on the Robin and Hawk cameos in Part 1, Part features pretty much the entire Titans lineup, making it clear that this series still exists on its own Earthy and hasn’t been rolled into the Arrowverse.
The Doom Patrol
The Doom Patrol also appear during this closing multiverse montage. Their appearance also confirms that Titans and Doom Patrol take place on different worlds, despite Titans: Season 1 introducing the characters.
Derek Mears as Swamp Thing
Though his show was abruptly canceled after one shortened season, Swamp Thing at least has his place in the multiverse cemented thanks to Crisis. Again, this cameo confirms the series is set on its own world and isn’t connected to Titans or Doom Patrol.
Crisis closes out with another big cameo, as Barry brings together his new superhero neighbors to form a team. The unnamed group’s headquarters looks an awful lot like the one in the Super Friends cartoon, and we even hear superhuman monkey Gleek and see his opened cage. Can the Wonder Twins be far behind?
