Famke Janssen and Edi Gathegi both played characters in Marvel's X-Men movies. Janssen played Jean Grey/Phoenix in X-Men (2000), X2 (2003), X-Men: The Last Stand (2006) and X-Men: Days of Future Past (2014) while Gathegi played Darwin in X-Men: First Class (2011).
In addition to Terry O'Quinn appearing in this series, at the same time he is starring in Amazon's "Patriot".
John Terlesky directed three of the episodes in this short-lived series, of which this episode is the first.
Famke Janssen may seem a little implausible playing Ryan Eggold's mother but there's actually a 20 year age gap between the two.
