We round up the biggest stories in geek TV, which affect businesses across the landscape.

Critical Role, the weekly Twitch streaming show that features voice actors playing Dungeons & Dragons, has raised over $3.7 million in the first day of its Kickstarter campaign  to produce an animated special built around the characters the players took in their first campaign.

Critical Role: The Legend of Vox Machina Animated Special will be written by Jennifer Muro (Star Wars: Forces of Destiny, Spider-Man, more), animated by Titmouse (Big Mouth, Venture Brother, Metalocalypse, more), and voiced by the stars of Critical Role, playing their characters.  At the current funding level, it’s planned as an 88-minute special for release in 2020, but by the time this campaign wraps up on April 19, it will likely be much more.  This will be another big boost for Dungeons & Dragons, on which Critical Role has already had a major impact.

The CW’s Riverdale shut down production on Season 4 (see "The CW Renews Everything") Monday after learning of series regular Luke Perry’s death.  Perry’s death followed a stroke last Wednesday.  He played Archie’s father Fred Andrews on the series.  It’s not clear how long production will be suspended.  In a statement released to the Hollywood trades, series executive producers Greg Berlanti, Sarah Schechter, Roberto Aguirre-Sacasa, and Jon Goldwater, along with Warner Bros. Television and the CW, said:

"We are deeply saddened to learn today about the passing of Luke Perry.  A beloved member of the ‘Riverdale,’ Warner Bros. and CW family, Luke was everything you would hope he would be: an incredibly caring, consummate professional with a giant heart, and a true friend to all.  A father figure and mentor to the show’s young cast, Luke was incredibly generous, and he infused the set with love and kindness.  Our thoughts are with Luke’s family during this most difficult time."

Production on IDW Publishing’s Wynonna Earp has been delayed due to lack of funds, according to The Hollywood Reporter.  Syfy, which airs the series, released a statement reaffirming its commitment to the show, and IDW released a statement that said, in part, "We are in the process of working out the details for how the Wynonna story will continue and will share new details very soon."  The news comes in the wake of the departure of the company’s CEO in the midst of massive losses (see "IDW CEO Out as Company Posts $36 Million Loss").

AT&T is in the process of restructuring WarnerMedia as it moves to put its mark on its new acquisition, according to Variety.  Big changes around geek shows include the departure of HBO CEO Richard Plepler and the transfer of Cartoon Network from the Turner group to Warner Bros.  Some are concerned that turnover at the top of WarnerMedia divisions may portend creative declines.

The third Walking Dead series is in "active development," AMC COO Ed Carroll told analysts in a conference call, as reported by The Wrap.  The news comes as the core series hit a ratings low with the current season (see "’TWD’ Hits Ratings Low"), although it’s still among the top shows on TV.

Syfy has picked up the Resident Alien series, based on the Dark Horse comic.  The pick-up follows a pilot order last June (see "Syfy Orders ‘Resident Alien’ Pilot").  Alan Tudyk stars.
