The new, Christopher Meloni-starring Syfy show Happy!, premiering Dec. 6, is your average, run-of-the-mill, corrupt-ex-cop-wakes-up-to-find-his-new-friend-is-a-Patton-Oswalt-voiced-flying-cartoon-horse story.

Wait, whaaat?

“[My character] is Nick Sax, and he is an ex-detective, disgraced, who now makes his living killing people,” says Meloni. “In the midst of a job — i.e. an assassination — I suffer a heart attack, I wake up in an ambulance, and all of a sudden, in front of me, hovering, is this tiny, blue, flying unicorn called Happy.”

What attracted the Law & Order actor to this adaptation of writer Grant Morrison and artist Darick Robertson’s graphic novel? “I just thought it was outlandish.” says the actor. “I thought, This is either going to be awesome or it’s not going to work. I thought, I want to go all in!”
