We’re really liking this new show! The premise is fresh, the look is quietly dark and misty (they shoot in Oregon) and the chemistry is great. And tonight we get a special treat in the form of a very cool guest star. Here are a gallery of pics, two clips and the episode synopsis to get you ready:

Nana Visitor (Star Trek: Deep Space Nine, Battlestar Gallatica) is a guest star on this Friday’s GRIMM – NBC‘s new hit series.

She plays a GRIMM monster – The Mellischwuler (Queen Bee of the Mellifer community). Mellifers are bee-like creature that exists typically as part of a swarm, and in groups they operate with a hive mentality. They live in man-made life-size hives they build in the attics of houses, where they harvest their own apitoxin (bee venom). Mellifers are clarions – they send the warning call within the creature world.

Episode Description:
A SOCIAL MEDIA CRAZE DISGUISES A STRING OF BIZARRE MURDERS – The station is abuzz as Nick (David Giuntoli) and Hank (Russell Hornsby) are called to a case where an innocent flash mob results in a gruesome homicide. As Nick delves further into the investigation, he learns more about his unique family history, and finds himself at odds when he and Hank are assigned to protect a dark character from his recent past. Bitsie Tulloch, Silas Weir Mitchell, Sasha Roiz and Reggie Lee also star.

From the creative minds behind the acclaimed series’ Angel, Buffy the Vampire Slayer and X-Files, comes a new world of police work where all cases have a storybook connection…but not always happily ever after. GRIMM, debuting on NBC this fall, is a provocative police procedural mixed with supernatural mythology, inspired by the classic Grimm Brother’s Fairy Tales.

Cast: David Giuntoli (“Turn The Beat Around”), Russell Hornsby (“Lincoln Heights”), Bitsie Tulloch (“Quarterlife”), Silas Weir Mitchell (“Prison Break”), Reggie Lee (“Persons Unknown”) and Sasha Roiz (“Caprica”)

Executive producers: Sean Hayes and Todd Milliner (“Hot in Cleveland”), Jim Kouf (“Angel”) and David Greenwalt (“Buffy the Vampire Slayer”).

Grimm airs Fridays at 9/8c on NBC.
