Last week, comic book fans went nuts upon hearing the news that Tom Welling would once again suit up as Clark Kent/Superman for The CW’s upcoming Arrowverse crossover “Crisis on Infinite Earths.” The news of the Smallville world crossing over with the current DC TV landscape was exciting to many, leading some to theorize that another Smallville actor could be making an appearance.

Michael Rosenbaum starred as Smallville‘s Lex Luthor, former friend and archenemy to Superman. He’s arguably the series’ greatest asset, and so, fans were clamoring for the announcement that he’d be joining the crossover. Unfortunately however, Rosenbaum himself announced that he would not be appearing.

In a Twitter post, Rosenbaum confirmed that he was asked to appear in the crossover, but wasn’t given any idea about what Luthor would be doing, as well as saying that the pay for him appearing was rather low:

“Friends, many of you have tweeted and asked me about joining the Infinite Crossover,” Rosenbaum wrote. “I can’t tell you how much this means to me. I’ll just be straight up about this. WB called my agents Friday afternoon when I was in Florida visiting my grandfather in a nursing home. Their offer: No Script. No idea what I’m doing. No idea when I’m shooting. Basically no money. And the real kick in the ass “We have to know now.” My simple answer was “Pass”. I think you can understand why. I hope this answers all of your questions. Lovingly Rosenbaum.”

It’s rather unfortunate to think that Rosenbaum won’t be acting alongside Welling and Erica Durance, whose Lois Lane was also confirmed to be in the story. That being said, it isn’t hard to see why he said no. It’s surprising that he said WB had no idea what Luthor would even be doing, while still trying to get such a quick answer. It would seem that at the time of asking, WB and CW were more considered with “which DC actors can we pull for this,” instead of figuring out the full scope of the story.
