The formerLostactor, who portrayed Dr. Jack Shephard in the ABC sci-fi series from 2004 until 2010, is set to make his debut in Peacock’sLast Light, premiering next month.

Fox’s involvement in the series marks the first time he’ll be returning to screens in seven years, and his first television role since 2010.

As shown in the series' action-packed trailer, which was released on Tuesday, Andy is in a race against time as he works to reunite his family amid the ongoing oil disaster.

“Chaos poses the greatest danger,” British government employee Karl Bergmann (Tom Wlaschiha) says in the trailer, while another voiceover can be heard saying, “There is a lot at stake here.”

“Once you’ve seen the truth, it becomes your responsibility to help other people too,” adds wife Elena (Froggatt) to Andy. “We’re going to do this together, every step of the way.”

In a chilling final moment, Andy says, “Just tell me what I’ve got to do.”

In a statement shared on Tuesday, executive producer and director Dennie Gordon said in part: “We knew that we were telling a ripped from the headlines story. But we didn’t realize that things would escalate as they have, and that we would be living all these events as we were shooting in real time.”

In June, the 56-year-oldParty of Fivestardiscussed his previous decision to step away from acting, as well as why he was coming out of “retirement” for the role in Peacock’s limited series.

“I kind of had a bucket list in my mind of things that I wanted to accomplish in the business, and after I didBone Tomahawkin 2014 that had kind of completed the bucket list,” Fox said at the Monte-Carlo Film Festival,Varietyreported. “I wanted to do a Western. It’s a very odd Western, but it’s a Western. And so that sort of completed the bucket list.”

“At that time in my life, our kids were at an age where I felt like I needed to really reengage,” he continued. “I had been focused on work for some time, and [my wife] Margherita had been running the family so beautifully, but I felt like it was time to be home, and I really felt like I was retiring from the business, and working on other creative elements that are really personal to me – some music and writing.”

However, Fox told reporters that things changed when he got the opportunity to be both the executive producer and star ofLast Light.

“I kind of got to a point where I thought that maybe the bucket list included executive producing,” he said. “I’d never done that before. The opportunity to be involved in ‘Last Light’ came along, and so I wanted to give it a shot. And it felt like the right time.”

“So it just all kind of came together. It felt like it was the moment to jump back in, and see how it felt to be in front of a camera again, and to act again,” Fox added. “And it was surprisingly rewarding. And I felt really good doing it, and with this incredible group of people, and the collaborative aspect of it, and how well we all bonded, how much we believed in the project. And it turned out to be a fantastic experience.”
