The Arrowverse's upcoming Crisis on Infinite Earths crossover event is the gift that keeps on giving, as Elizabeth Tulloch shares a photo of her with Superman actors Tyler Hoechlin and Tom Welling (Smallville). The CW first teased Crisis on Infinite Earths nearly a year ago, during the Elseworlds crossover that united ArrowSupergirl, and The Flash. This year's event is even more ambitious, as it will feature characters from all three shows, plus Legends of TomorrowBatwoman, and Black Lightning. The Arrowverse will air three episodes of the event this December, with the remaining two airing in January. The crossover is expected to have massive implications for all of its shows, especially Arrow and The Flash.

Though Crisis on Infinite Earths will feature several exciting guest stars, Tulloch, Hoechlin, Welling, and Erica Durance have received quite a bit of attention for their roles. Tulloch and Hoechlin are the Arrrowverse's Lois Lane and Clark Kent. They last appeared in Elseworlds, where Superman left Earth to his cousin Supergirl's care. Meanwhile, Welling and Durance played the same characters on Smallville, which ran from 2001-2011. The crossover will also feature a third Superman, as the Arrowverse's own Brandon Routh suits up as the Kingdom Come version of the character. Routh usually plays Ray Palmer/the Atom on Legends of Tomorrow after being introduced on Arrow.

On Instagram, Tulloch posted the photo with Welling and Hoechlin earlier today. In it, all three are seen on the Kent Farm. Tulloch captioned the photo "Lois and Clarks." Last week, Durance posted a similar photo of her reunion with Welling, which also looked like it was on the Kent Farm. Welling's wearing the same outfit in both photos, suggesting they're from the same scene. Though Routh's Superman hasn't appeared in photos with any actors playing Superman or Lois, The CW shared a solo photo of him in his new superhero duds. Routh previously played Superman in 2006's Superman Returns. Check out Tulloch's Crisis on Infinite Earths photo below:

Like Tulloch and Hoechlin, many of the actors guest-starring in Crisis on Infinite Earths are Arrowverse returnees. Jon Cryer will reprise his role as Lex Luthor after playing the villain last season on Supergirl. LaMonica Garrett will also return as The Monitor, the de facto leader of the crossover. He appeared in Elseworlds to inform Oliver Queen about the crisis to come. He also showed up in several season finales this spring, most notably Arrow's. There, he came to collect on the deal Oliver made with him during Elseworlds to save Barry Allen and Kara Danvers. Garrett will also play the villainous Anti-Monitor, though that character hasn't been glimpsed yet.

Until now, it wasn't known for sure which characters would interact during Crisis on Infinite Earths, including the different versions of Superman and Lois Lane. Tulloch's behind-the-scenes photo suggests it's at least a possibility, since she, Welling, and Hoechlin were all on set at the same time and in the same location. If the Smallville and Arrowverse characters appear onscreen together, it seems likely that Routh's Superman may too. Even one shot with all five characters seems like too good of an opportunity for the Arrowverse to pass up.
