Lots of geek TV news as the biz heads for San Diego, and we round it up here.

The Walking Dead has halted production on its eighth season after a tragic on-set accident involving one of the series’ stuntmen. According to Variety, stuntman John Bernecker reportedly suffered a serious head injury after he missed a safety cushion after a 20-foot fall and instead landed on a concrete floor. He was transported to an Atlanta-area hospital, where he was declared brain dead and taken off life support.

Coweta County Coroner Richard Hawk told Deadline that Bernecker died of blunt force trauma at 6:30 p.m. EDT on Wednesday. Federal workplace watchdog OSHA and stunt performer union SAG_AFTRA are both investigating the accident. Bernecker is believed to be the first on-set death for a stuntman to occur in the United States in more than 17 years.

Bernecker had worked on more than 90 films, including a number of recent releases such as Black Panther, Logan, and Get Out.

The producers of the hit Sherlock series are taking on another literary classic: Bram Stoker’s Dracula. Variety reports that Mark Gatiss and Steven Moffat will write the series, which will have a similar format to Sherlock, with a short series of feature-length episodes. The two are currently working on solo projects, so work hasn’t yet begun. Talks are underway with BBC, which ran Sherlock in the U.K.

Snowpiercer has cast its female lead reports Deadline. Jennifer Connelly will star opposite Hamilton alum Daveed Diggs in the TNT pilot (see “Additions, Changes To Upcoming Geek Shows”). Connelly will play Melanie Cavill, a first class passenger responsible for making daily announcements over the train’s PA system. The postapocalyptic allegory for class warfare finds Cavill more sympathetic to the lower class passengers, which include Diggs’ prisoner Layton Wells, than most VIPs. The pilot is being directed by Doctor Strange helmer Scott Derrickson.

Amazon’s take on The Tick has a trailer. The new Amazon Prime series drops August 25 (see “’The Tick’ Gets Series Order”). August also sees the return of The Tick to comics (see “'The Tick' Comics Return”).
