Nolasco played Sucre, Scofield’s initial cellmate in the Fox series, a hopeless romantic driven by his love of his eventual wife. Dunbar, meanwhile, played C-Note, a hardened former soldier who proves himself after manipulating himself into the show’s titular escape (the first one, that is, because of course Prison Break featured escapes from multiple heavily guarded facilities during its four-season run).
It’s Knepper’s return, though, that’s most notable; in many ways, his character, the complicatedly loathsome murderer, rapist, and pedophile Theodore “T-Bag” Bagwell was the show’s breakout character, appearing almost as often as protagonist Scofield himself. Presumably, everyone involved resigned themselves to the fact that the new limited series just wouldn’t be Prison Break without his supposed charms, serving as the monstrous Wile E. Coyote that gets out-thought at every step by Michael’s heavily tattooed roadrunner.
At this point, Fox has almost assembled a complete team for its attempt to break back into people’s homes with more tales of ludicrously complicated escapes; the only holdout from the show’s main cast—the surviving ones, anyway, not that that matters all that much in Prison Break land—is William Fichtner, who played eventually disgraced FBI agent Alex Mahone from the show’s second season until its 2009 conclusion.
