UPDATED: I’ve learned that NBC has renewed freshman drama Grimm for a second season with a 22-episode order. That may be be the first of several early pickups of existing series at the network, though despite rumors nothing else is expected to come down today. A low-key addition to the schedule on Friday, Grimm has held its own, even growing when given a chance to run uninterrupted for several weeks. Created by David Greenwalt, Jim Kouf and Stephen Carpenter, Grimm stars David Giuntoli as a homicide detective who is also a Grimm, hunting supernatural baddies. It is produced by Universal TV and Sean Hayes and Todd Milliner’s Hazy Mills Prods. This is the first NBC series to get a renewal for next season. The move comes on the heels of CBS picking up 15 shows earlier this week.
