Last summer at the Comic-Con International in San Diego, it was hinted that some surprise guests would be showing up in the series finale of Superman & Lois which airs tonight (December 2) on The CW. While this post isn’t meant to confirm or deny any fan speculation, there has been a lot of it in the past week, and this post is a way in which we can share what’s been talked about… you know, in case one of these actually does happen.

We can tell you that almost all of the former series regulars for Superman & Lois are confirmed to return — a list that includes Emmanuelle Chriqui as Lana, Erik Valdez as Kyle, Inde Navarrette as Sarah, Wolé Parks as John Henry, Tayler Buck as Nat, Sofia Hasmik as Chrissy, and possibly more.

For what it’s worth, though, here’s some of the speculation, in no particular order, plus a few extras we threw in for this post. Enjoy:

Barry Allen/The Flash (Grant Gustin) or Oliver Queen/Green Arrow (Stephen Amell): Since the finale of Superman & Lois is the effective end of the Arrowverse (even if it’s not on Earth-Prime), what if the show revisits one or both of the heroes who started it all? Barry could surely find a way to travel Earths and Oliver is still the Spectre last we checked, so… maybe? Though they might not be as likely as….

Kara Danvers/Supergirl (Melissa Benoist): It was her show that first introduced us to Tyler Hoechlin’s Superman. Is there a Supergirl on this show’s Earth? Now is as good of a time as any to find out.

John Diggle (David Ramsey): He was there at the start of the Arrowverse ever since the first episode of Arrow, and unlike those folks up above, he has appeared on Superman & Lois. If he does show up, though, he better have a green ring!

The Justice League: Peacemaker ended with a Justice League we’ve had to say goodbye to; what if Superman & Lois does the same thing, either with established characters, or folks just cast as a special one-shot treat?

Bruce Wayne (David Giuntoli?): Bitsie Tulloch has hinted that Grimm fans should be sure to tune in, so we’re assuming a Grimm cast member, most likely her real-life husband David Giuntoli might be appearing in the finale. Popular speculation has him playing Bruce Wayne if he was to show up.

Lucy Lane (Jenna Dewan): Jenna Dewan is super busy with The Rookie but since she missed Sam’s funeral, maybe she’ll be back for the show’s last hurrah at least?

Tom Welling: Because why not.

Jon-El (Jordan Elsass?): The Bizarro World version of Jonathan Kent is still out there, as far as we know, and that storyline was revisited as recently as the penultimate episode. What if this other Jonathan still looks like the first actor to play this role, Jordan Elsass? Or could we see Michael Bishop donning the 1990s-inspired suit and red pants?

Tom Cavanagh (Again): We saw Tom Cavanagh as recently as episode 7 this season, playing Gordon Godfrey, but considering how many characters he played on The Flash, surely there’s one more in the tank before all is said and done? A Wells, a Thawne, a Pariah…. there are lots of possibilities out there.

What do you think? Are any of these speculations correct or are we BS-ing you this whole time? Leave your speculation in the comments below and ENJOY THE FINALE tonight at 8PM ET/PT on The CW!

Several weeks ago, Smallville stars Michael Rosenbaum and Tom Welling took their “TalkVille” podcast and made it a live performance combined with their exclusive “Smallville Nights” that they’ve had on the convention circuit. Their first stop — extended to two shows after the first sold out — was at the Bourbon Room in Hollywood.

I’ve long said that for fans of the show, it’s costly but you need to do “Smallville Nights” at least once. It’s an interactive thing where fans get to re-enact scenes with the actors themselves, and all get the chance to offer the perfect delivery for “I am the villain of the story!” At the live TalkVille event, this was especially cool because each and every attendee got the chance to do the thing.

The “TalkVille” element of the show was different from I at least hda originally expected — it was more of a freeform discussion between Rosenbaum and Welling, discussing some of their favorite memories of the show, and answering questions from the audience. It would have been fun to see them do an actual show from the podcast in front of the audience, but realistically, that could be a recipe for disaster in case any cuts are needed or anything like that.

One strong thing I felt when watching Tom and Michael on stage is that the source of one of the criticisms of the podcast seems to be identified: Sometimes it has been noted that Michael would interrupt or speak over Tom, when it appears the actual problem is that when recording the podcast, there’s a slight video delay so Michael might not even realize he is talking. So, it’s not a matter of being rude, but perhaps a technical difficulty that might be solved in a future show or two where Tom actually recorded in person at the studio. Both guys (and Ryan!) got time to talk at this event, and there wasn’t any such interruption.

There were some stories told at the event that I didn’t even know or realize — for example, how Kristin Kreuk helped Tom with his audition. Both had a gratitude for the show and I think events like these really make them see it first hand. Tom joked more than once that he tried to cancel the event, but he seemed to do really well with it when it happened. I was touched and surprised that I got a few shoutouts in person… and even hugs when the guys realized I was there! Sadly, there weren’t any individual photo ops or anything, but the memories will remain very strong, and there was a very cool “poster” given to all attendees with awesome artwork by Mickael Journou (MikePosters on Instgram). You can see that artwork up above; hopefully it’s okay that it was used for this post. Apparently, this art was also being sold on a T-shirt, but I didn’t see one!

Beyond getting to see two of the leads of Smallville, a great part of the night was a 45 minute to an hour intermission between Smallville Nights and the TalkVille presentation, and that was also a lot of fun because it gave the opportunity to meet other fans and talk. So many of us started watching the show at different times and it was so much fun to share those experiences with one another. After all, we were all there because of loving Smallville! It was just a lot of positivity and fun, and I met some cool people and hopefully made some cool new friends.

As someone who has covered the show since the beginning, it is also really fun to see Tom being joyful about talking about the show. It really highlights how overwhelmed he must have been when the show was on the air. I still can tell when fans are recreating scenes from Smallville that he still thinks like a director, which is so cool. He’s also such a dad now. His shoes were sticky so he took them off to reveal neon socks, which were actually not as uncool as he thought because…. maybe it was kryptonite. Haha. Still, all in all a good time!

Any negative feedback? A venue with easier parking and a less expensive menu would be nice, but as for the show itself, it was a great time. If and when the TalkVille guys do this again, I highly recommend that you check it out.

Season 3 of Superman & Lois ended with what looked like a fatal showdown between Superman and Doomsday, reminiscent of the events of the legendary Superman #75 comic book by Dan Jurgens over 30 years ago. Now, some new comments from Bitsie Tulloch combined with some analysis from our good friend Ben Rolph of the Ben’s Take YouTube channel (formerly TheDCTVShow) begs the question: Is Superman & Lois adapting “The Death of Superman” in Season 4?

In the original comics, the Death of Superman was followed by an acclaimed storyline called “Funeral for a Friend” as the folks in Superman’s orbit as well as the people of the Daily Planet deal with the loss of Metropolis’ greatest hero. That led months later to a “Reign of the Supermen” story where four folks – including John Henry Irons, making his first comic book appearances – tried to become Metropolis’ new hero, with some including the Cyborg Superman claiming to the the real steel deal.

So what made Ben think they’re going full force into “Death of Superman” territory, and why do we agree with him?

Bitsie Tulloch recently appeared at the Metropolis Celebration in Illinois this past weekend, and she made a certain major tease:

“You guys are not going to believe the first episode,” she teased. “It’s bananas. It’s emotional. What they did was based on one of the comics. It was a very bold decision on their part to do to do this and to pull it off for the first episode of Season 4.”

Bold decision? Based on the comics? Killing Superman would be pretty darned bold, yeah?
