The Lazarus Project writer and creator Joe Barton has addressed the possibility of a second season.
The series follows protagonist George (I May Destroy You's Paapa Essiedu) as he is recruited by a secret organisation that has the power to revert time to prevent extinction-level threats. Meanwhile, he has to figure out what the time loop he's stuck in is all about.
The good news is that Sky's sci-fi series does leave the door open for more at the end of its first run. However, Barton doesn't have a clear timeline of future instalments at present.

"I've just got some random ideas," he told RadioTimes.com.
The showrunner also revealed he wasn't exactly sure where the first season would end when he was writing, but that somehow it all managed to fit together.
"It wasn't until I wrote the last episode that I worked out what the ending was going to be," he said.
Although he didn't originally envision the series as a multiple-arc story, Barton explained that the first chapter "does open it up for another series".
"But it was certainly not guaranteed that [a second season] would happen."

As where he would go with a second instalment, Barton said he's definitely interested in digging deeper into the corrupted morals of those working on The Lazarus Project.
"There's an almost God-like aspect, they have this incredible power – they live in this world where they can manipulate space and time and they could live without consequences if they want to... and how does that corrupt them? How does it change the way they view morality? So it's something I think is interesting and we want to carry on exploring."
Alongside Essiedu, the series also stars Anjli Mohindra as Archie, Rudi Dharmalingam as Shiv, Caroline Quentin as Wes, Salóme Gunnarsdóttir as Greta and Lorn Macdonald as Blake.
The Lazarus Project is available to watch on Sky TV and NOW.
