While promoting his new movie "The Wife," with Glenn Close, Christian Slater shared the news that the upcoming fourth season of hit show "Mr. Robot" might be its last.

Talking to Collider, Slater said: "I believe [Season 4] will be the last. [Series creator] Sam [Esmail] always said it was going to be somewhere in that zone, and he didn’t want to go further than what he could creatively contribute to that story line. So, I think that Season 4 will be it."

He also said he's also not sure how much he'll appear in Season 4: "I think they’re in the writers' room, as we speak, putting it all together, but I have no idea what it’s gonna be, or if I’m gonna be floating in and out of scenes. I have no idea, so we’ll see what happens."

The mind-bending hacktivist series debuted on USA in 2015, netting two Golden Globe nominations each for Slater and lead Rami Malek, with one Globe win for Slater and an Emmy win  Malek.

Both their careers have gotten a huge boost from the show: Malek is starring as Queen frontman Freddie Mercury in "Bohemian Rhapsody," and also has a remake of "Papillon" coming out August 24. And he's working with Esmail on "American Radical," based on a Muslim FBI agent’s memoir about infiltrating an al-Qaeda-controlled terrorist cell.

The Wrap reached out to USA, who declined to comment on Slater's comments.

Season 4 stars filming in November (according to Comic Book Movie) and no premiere date has yet been announced.
