Variety:

Emerald Fennell, the Oscar-nominated director of “Promising Young Woman," is taking on a different kind of vigilante. She has been tapped to write “Zatanna," a big-screen adaptation of the DC Comics heroine.

The movie, from Warner Bros.’ DC Films and J.J. Abrams’ Bad Robot Productions, is set to be released theatrically.

The upcoming installment in the DC Extended Universe will be Zatanna’s first franchise appearance. She is known for her involvement with the Justice League, though the character has never appeared in a DC movie. Serinda Swan previously portrayed Zatanna, marking the superhero’s live-action debut, on later seasons of The CW show “Smallville." The role of Zatanna has not been cast yet.

This had been rumored to be one of the “smaller" projects WarnerMedia is considering as a direct-to-HBO Max exclusive.

I’m guessing Fennell’s take is strong enough to be the reason why the movie is heading to a theatrical release.

Either way, very excited to see how this plays out!
