Wentworth Miller and Dominic Purcell are set to be reprising their roles as the incarcerated brothers Michael Scofield and Lincoln Burrows.
Actress Sarah, 38, also said in a recent interview that she was “trying to make it work”, referring to signing up to the Prison Break revival.
US broadcaster confirmed back in August last year that the show would be returning with CEO Gary Newman saying: “It’s going to bring back both brothers, Wentworth Miller and Dominic Purcell.”
“I would describe it as a bit of a sequel. It picks up the characters several years after we left them in the last season of the show,” explained co-chairman Dana Walden.
The new story has been written by Prison Break creator Paul Scheuring.
Despite the fact that Michael died at the end of the series, the plot will give a “logical and believable” explanation for how the characters survived and are “still moving around the world”.
While composer Ramin Djawadi told Express.co.uk that he would “absolutely” return to the series to work on the music.
It was originally thought that the new limited run season would be comprised of 10 episodes but it is now uncertain how many instalments there will be.
