Following a pilot order last September, SyFy has officially ordered Happy! to series.

Happy!, which stars “Law & Order: SVU” alum Christopher Meloni as Nick Sax, detective turned hired killer, is based on the Grant Morrison and Darick Robertson Image Comics miniseries of the same name.

Here's the network's official series description: "The series follows Nick Sax (Christopher Meloni, “Law & Order: SVU”) – an intoxicated, corrupt ex-cop turned hit man – who is adrift in a world of casual murder, soulless sex and betrayal. After a hit gone wrong, his inebriated life is forever changed by a tiny, relentlessly positive, imaginary blue winged horse named “Happy” (Bobby Moynihan, “Saturday Night Live”)."

Along with an official series order, the first look at Meloni as Sax has been revealed by the network.

Joining Meloni in the series are Patrick Fischler (Lost, Mad Men), who is set to play Smoothie, Ritchie Coster (Blackhat) who is set to play Mr. Blue aka Leonardo Scaramucci, and actress Zabryna Guevara (Gotham), who will play the beleaguered single mom Amanda Hansen,

The series order for Happy! follows that of the Superman prequel, Krypton, and is put of the network's effort to re-band itself as more of a fandom-based network.

The pilot episode was written by Grant Morrison and Crank writer-director Brian Taylor, with Taylor also stepping behind the camera to direct. Morrison, Taylor and Meloni all serve as executive producers, along with Neal Moritz, Pavun Shetty and Toby Jaffe of Original Film, and showrunner Patrick Macmanus.
