We couldn't wait to check out Netflix's Unstable, created by, let's face it, the iconic Rob Lowe, and his hugely talented son, John Owen Lowe. Having premiered on the platform last month, the eight-episode series tells the tale of an endearing and eccentric biotech entrepreneur, inventor, and genius as he navigates the aftermath of recent difficulty in his personal life. The series is filled with brilliantly quick, dry humor, and of this latest take on the modern workplace comedy, our eyes are on rising star Rachel Marsh, who plays one of several quirky biotech engineers employed by the company that the elder Lowe's character, Ellis Dragon, helms. Marsh ditched her improv instincts to play 'Luna Castillo', telling us that workplace comedy is what she grew up loving and gravitating towards. Referring to the show's co-creator as 'Johnny', Rachel shares that John Owen Lowe had a huge part in making the choices for what to do with her Luna, and that the pilot was in fact written while he was in college. While Rachel continues to hone her craft, performing at Upright Citizens Brigade, we talked to the up-and-comer all about her prominent and pivotal project, how it's made her grow as an actor, and the role she's thrilled to call deeply collaborative.
