“Mr. Robot” star Christian Slater has dished out behind-the-scenes details about the show, including his fear that he was not going to appear in the series after Season 1, according to IndieWire.

“It was something I was a little concerned about, because I was enjoying playing the part so much,” Slater, who plays Mr. Robot in the series, told IndieWire’s Michael Schneider in an interview for the Screen Actors Guild‐American Federation of Television and Radio Artists.

Slater, 47, said that towards the end of “Mr. Robot” Season 1, when it was revealed that Mr. Robot was Eliot’s (Rami Malek) deceased father, he feared he would not be called back to work, believing his stint was done.

“And it definitely would’ve been a bummer if that had been it … so when we did the graveyard scene in Episode 9, I didn’t know what was going to happen in Episode 10. So I called Sam [Esmail] and said, ‘Well, dude, I loved working with you but I guess that’s it, right?’ And he said, ‘Oh, come on! — Elliot without Mr. Robot is like Bruce Banner without the Hulk.'”

The actor also pointed out in the interview what he thought was the irony in USA Network's decision to air “Mr. Robot,” a show that features sharp criticism of capitalism. “It was fascinating that USA was willing to do a show about taking down a huge conglomerate — when they are a huge conglomerate,” Slater said. “The thing is riddled with irony.”

Asked what moment during his work on “Mr. Robot” has been most memorable to him so far, Slater said that it was when he worked with extraterrestrial character Alf, during the the show’s ‘90s tribute episode in Season 2. “That’s the stand-out moment for me, particularly Season 2. Getting to work with him was something I will never forget,” Slater said.

“Mr. Robot” will be back for Season 3 in 2017.
