What makes this particularly surprising is that Anatoli Knyazev is a relatively minor figure at best in the movie; it's possible that many viewers would have no idea who he was at all. (For the record, he's the Russian warlord who kidnaps Lois in the beginning of the movie and later repeats that trick by kidnapping Martha Wayne. The character onscreen bears little similarity to the Starlin-created character, who — in DC's comic mythology — is better known by his nom-de-plume, the K.G.Beast.

Last year, Starlin told Heat Vision that he had renegotiated his deal with Marvel over its usage of Thanos, ahead of the character's onscreen debut in 2012's The Avengers.

"I'd like to have had a bigger piece of Thanos than I do, but when the first Avengers movie came out, Marvel and I — we renegotiated some things, so I get a taste out of this thing," he said. "I'm not becoming the next Bill Gates, but I'm getting a little something out of it." Literally, it seems, a little something.

In case Starlin's post seemed too much like a commercial for DC, he did throw a little shade at the end of his post, admitting that he'd yet to find time to enjoy BvS for himself. "Guess I'll finally have to sit down and watch the movie," he wrote.
