Taylor Schilling (Piper Chapman), Kate Mulgrew (Galina ‘Red’ Reznikov), Nick Sandow (Joe Caputo), Michael Chernus (Cal Chapman), Jessica Pimentel (Maria Ruiz), and Stephanie Andujar (Young Miss Rosa) starred together in MSNBC’s Mercy, which followed a handful of nurses at the eponymous hospital through their struggles at work and at home. Mulgrew played Schilling and Chernus’ mother.
Sandow was Scott’s Dad in one episode. Andujar played Deanna in two episodes. Pimentel appeared once as a female clerk.
Schilling and Chernus naturally were a good brother-sister fit on Orange given that they played a sibling duo as well on the series.
The series lasted one season before cancellation by the network.
