Five months after getting a pilot script order, Fox’s Prison Break revival has been officially ordered to series — and the cast is starting to be fleshed out.

Both Wentworth Miller and Dominic Purcell have signed on to reprise their lead roles, as brothers Michael Scofield and Lincoln Burrows, while TVLine hears that talks thus far are underway with both Sarah Wayne Callies (now starring on USA Network’s Colony ) and Robert Knepper , to return as Sara and T-Bag.

Miller and Purcell currently co-star on The CW’s
Legends of Tomorrow , which the actors said earlier this week will dictate their window of availability for the Prison Break revival, which is tentatively set to start filming this spring. Originally eyed as a 10-episode event series, Fox is now thinking closer to nine episodes, to begin filming as soon as late March.

"The story unravels on an international landscape — it’s not a domestic [plot],” Fox co-chariman/CEO Dana Walden said. “We open on a very international contemporary-feeling story.”
Walden said that Fox’s Prison Break continuation will take place during a period of time preceding “address” the events of the straight-to-DVD epilogue, The Final Break , in which a major character met his demise. Noting how many times the characters have broken out of prison, “It’s not a documentary!” she laughed.
