The first footage of Grimm's third season has surfaced, including Nick (David Giuntoli) as a zombie.

NBC posted a new video Thursday featuring a behind-the-scenes look at Giuntoli as Nick in full zombie makeup. The video shows the effects to make the actor's veins pop out more in addition to making his skin paler and his eyes redder.

See the video here:

 

"If Nick does survive this zombie state, he's going to be very dangerous," executive producer Jim Kouf told TV Guide Thursday. "There will be residual effects that will change him in a huge way."

Viewers last saw Nick become infected with zombie slime at the end of season 2.

In other Grimm spoiler news, Monroe (Silas Weir Mitchell) will be marrying Rosalee (Bree Turner) when the show returns in October. Grimm executive prodder David Greenwalt confirmed the wedding on Thursday but also teased that it wouldn't be entirely without problems.

"When you marry someone, you marry their family," Greenwalt explained. "Monroe's mother and father are old-school Blutbads - they may still even hunt, for all we know - and they think Fuchsbau like Rosalee are for eating, not for settling down with."

Speaking of romance, Hank (Russell Hornsby) will fall in love with his Wesen physical therapist in the upcoming season, much to the disapproval of her parents. Additionally, Sergeant Wu (Reggie Lee) will throw a fit after seeing a Wesen for the first time, according to the report.

At the end of the video, Giuntoli teases that more details will be revealed about Grimm's third season at their Comic-Con panel on Saturday, July 20. Enstars previously reported that Giuntoli, Mitchell, Hornsby, Lee and Turner will all be there in addition to fellow cast members Sasha Roiz (Captain Sean Renard), Bitsie Tulloch (Juliette) and Claire Coffee (Adalind). The show's executive producers will also be in attendance to tease the new season.

Grimm season 3 will be premiering on Oct. 25 at 9 p.m. on NBC.
