The premiere title for season 3 of Grimm was revealed Sunday by star Bitsie Tulloch.

Tulloch, who plays Nick's girlfriend Juliette on the show, tweeted a picture of the first script of the third season Sunday. According to the script, the first episode of the third season will be titled The Ungrateful Dead. The episode will premiere on Friday, Oct. 25 at 9 p.m. on NBC.

In addition to the photo Tulloch posted, she wrote, "Finishing up my summer reading. ‪#backtoschool tomorrow!" This seems to suggest that production is starting on season 3 of Grimm.

Enstars reported on July 11 about star David Giuntoli (Nick) made up to look like a zombie for the season premiere.  Alhough it is unclear if Giuntoli filmed anything substantial for the new season yet, he tweeted about not being on set Monday.

"Wish I was in PDX with my peeps for the opener. Luv u!" he tweeted Monday to Tulloch as well as co-stars Russell Hornsby (Hank), Reggie Lee (Sergeant Wu), Bree Turner (Rosalee), Claire Coffee (Adalind) and Sasha Roiz (Captain Sean Renard).

Many details have been leaked about Grimm season 3, including the fate of certain relationships. The most significant spoiler released thus far has been that Rosalee will be marrying Monroe (Silas Weir Mitchell). Grimm executive producer David Greenwalt revealed the news of their impending marriage to TVGuide.

Additionally, Hank will be falling in love with his Wesen physical therapist in the upcoming season, despite the parents of the physical therapist's disapproval.

More details are expected to be revealed at the upcoming Grimm panel at Comic-Con in San Diego, Calif. The show will have its own panel on Saturday, July 20 in which the cast and crew will be on hand to answer questions from fans and preview what's to come in the third season.

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