After four seasons and an Emmy Award for Best Actor, the 38-year-old star is saying goodbye to Mr. Robot.
"It's a tremendously emotional experience," Malek told ET at the season four premiere in New York City on Tuesday. "It has been since we began shooting this fourth season, and I know that it will be at the end of this night. It's a moment in my life that is profound and prolific."
The fourth and final season of the USA Network drama is set during the 2015 Christmas holiday and promises to be one filled with answers, hacking and blood.
"It is a very fulfilling and cathartic ending," Malek said. When asked if the series ending would lead to any potential follow-up movies or a possible revisiting of the characters, he shot down the idea, adding that the final episode is perfect the way it is. "If I may be so bold as to say, I think we nailed it," he said.
As the actor completed his time on Mr. Robot, he gave creator Sam Esmail one of his character, Elliot's, hoodies. As for what Esmail gifted him, it was something very sentimental.
"He put together the collection of all the CDs that Elliot uses to compile all the nasty people who have done the world wrong and framed them for me with a photo of the two of us," he shared.
And did he take anything from set? "Oh yeah," he said with a smirk, but kept mum about what exactly he snatched.
Prior to hitting the red carpet, Malek posted a nostalgic post about the series ending.
"In honor of our final season of Mr Robot airing this Sunday, October 6th, here is a moment from day 1, season 1," he began. "This has been one of the most powerful and profound experiences of my life, and I feel so fortunate to have been able to share it with all of you. Thank you for your undying love and support. This evening we will be celebrating the fourth and final season at the premiere in New York City. I can’t wait to share it with all of you on Sunday."
Among the Oscar winner's upcoming projects is starring as the lead villain in the James Bond movie, No Time to Die.
"I had an extraordinary time," Malek shared of being a part of the iconic franchise. "It is phenomenal every time you get to go to set and you see those three numbers, 007, on every piece of paper, on every badge, on every stage. It's extraordinary to be part of that legacy and that history, and I cannot wait for you guys to see that as well."
Mr. Robotkicks off its final season Sunday, Oct. 6 at 10 p.m. ET/PT on USA Network.
