The first trailer for The Penguin name drops a Batman character with a surprising tie to Catwoman.

If even comic book readers dont recognize that name, they can be forgiven.

Rex Calabrese is a relatively new addition to the Batman mythos.

Colin Farrell as The Penguin in The Batman

Raised by the Kyle family, Selina loses track of her past connections.

At least until Leo Leone gets out of prison and re-establishes himself as Rex Calabrese.

At this point, its not entirely clear how farThe Penguinwill go into that aspect of the mythos.

And if Reeves didnt want to address her backstory, then why choose Rex Calabrese as Ozs role model?

After all,Batmancomics are full of old-timey mobsters to name drop.

So isThe Penguinsetting up a huge storyline for Selina where she discovers that shes actually Rexs daughter?

Or is this just another easter egg?

Well find out later this year.

The Penguin streams on Max in 2024.
