This week’s episode of Peacemaker, “Ignorance Is Chris,” brought on a huge Superman cameo in the form of — spoilers past this point — Lex Luthor, played by Nicholas Hoult. But based on the promo for Peacemaker Season 2, Episode 7, “Like A Keith In The Night,” it seems like we’re getting another cameo from the feature film next week: none other than Sydney Happerson!!
If you’re asking, “Wait, who?” don’t worry, we’ve got you covered. In the promo, we see Rick Flag, Sr. (Frank Grillo) and Sasha Bordeaux (Sol Rodríguez) heading to a shadowy warehouse and freeing a man in prison orange from handcuffs.
“That’s the guy?” Bordeaux says.
“Luthor says that’s the guy,” Flag answers.
“What’s my reason for helping you?” says the mysterious, shaded man.
While the closed captions on the promo are no help — he’s credited as “SPEAKER” — and guesses online range from David Harbour’s Frankenstein from Creature Commandos, to Superman (David Corenswet), to even Deathstroke or KGBeast… Well, it’s almost definitely Sydney Happerson, who was played by Stephen Blackehart in Superman.
In case you can’t recall the name immediately, he’s the tall guy with the mustache who worked at LuthorCorp, and eventually sort of turned against Lex once the baddie started destroying Metropolis. So what’s he doing in prison? Well, he was also instrumental in destroying most of Metropolis, as well as multiple attacks on Superman, and massive destruction to the city prior to that as well. So yeah: prison.
Here he is saying, “Lex, the rift is almost here!” in a very silly voice:

In the movie, Happerson is a scientist, while in the DC Comics source material, he’s more specifically Lex Luthor’s assistant (as well as a scientist). Regardless, while it looks like a second Nicholas Hoult cameo may not be in the offing, we’re getting the next best thing — at least plotwise — a guy who intrinsically understands how portals work… Though not as well as Mr. Terrific (Edi Gathegi).
