Fox has ordered a 13-episode second season of “Sleepy Hollow,” making the fantasy thriller the first fall debut to be renewed for a sophomore run.

Renewal arrives just three episodes into “Sleepy Hollow’s” first season.

“Sleepy Hollow” ranks as Fox’s most successful fall drama premiere in over a decade. The program opened to 10 million viewers during its premiere, a number that blossomed to 13.6 million after three days of time-shifted viewing were accounted for. “Sleepy Hollow” has also retained a impressive number of its viewers since the show’s launch, even when faced with stiff broadcast competition that includes NBC’s “The Voice.”

“’Sleepy Hollow’ has proven to be a risk well worth taking – it’s a conceptual blast unlike anything else on television and it all holds together with inventive writing and a fantastic cast,” said Fox chairman of entertainment Kevin Reilly. “I can’t wait for fans to experience what else is in store for this fall and even more of this wild ride into season two.”

“Sleepy Hollow” stars Tom Mison and Nicole Beharie, and airs Monday nights at 9 p.m. on Fox. It is produced by Alex Kurtzman and Roberto Orci’s K/O Paper Products in association with 20th Century Fox TV.
