Sydney Sweeney, Euphoria and White Lotus star has joined the cast of Sony’s web of Marvel comic book character tentpole for their latest film, Madame Web. Sweeney’s role in the film has yet to be announced. It was previously reported that Dakota Johnson had been cast as the title character.

In the comics, Madame Web is a paralyzed elderly woman with Myasthenia Gravis, a chronic autoimmune disorder that requires her life support system to be connected to a system resembling a spider web. Although plot details are still in the dark, Madame Web is introduced in the comics as a blind clairvoyant mutant whose abilities benefit Spider-Man and the likes of his allies like Spider-Woman. Given her condition, she’s never battled a villain herself.

S.J. Clarkson, who’s worked on the darker Marvel series Jessica Jones and The Defenders, both of which have been moved from Netflix to Disney+, is set to direct Madame Web. Morbius writers Matt Sazama and Burk Sharpless will write the screenplay for the film.

While fans wait to hear more details on the project, Sydney is currently filming Tony Tost’s directorial debut National Anthem with Simon Rex, Halsey, and fellow Euphoria co-star Eric Dane. The White Lotus actress recently launched her own production company, Fifty-Fifty Films, and is developing The Players Table, a new TV adaptation of Jessica Goodman’s YA novel They Wish They Were Us, also starring Halsey.
