He plays one of Frank Underwood's closes (and, er, intimate) allies in House of Cards, but Nathan Darrow has now joined the cast of Gotham's second season as Victor Fries, a.k.a. Mr. Freeze. The character is set to appear in episodes twelve and thirteen, and he's described as follows: "Though ferociously smart and eminently capable in his work as one of Gotham’s preeminent cryogenics engineers, Victor struggles to make meaningful connections with others. The one exception is his wife, Nora, who has tragically fallen ill with a terminal disease. Victor’s love for Nora knows no bounds, so as her condition worsens, he goes to extreme measures to figure out a way to freeze her before she dies. This harrowing journey leads to his transformation into the legendary DC villain, Mr. Freeze." Nora has not yet been cast in the series, but it sounds like this is yet another bad guy whose origin story will play out before Bruce Wayne becomes Batman. The villain last appeared in live-action in 1997's Batman & Robin where he wasplayed by Arnold Schwarzenegger.
