The latest geek TV roundup brings big news for fan favorites.

Star Trek: Discovery has discovered a new showrunner. After the departure of showrunners Aaron Harberts and Gretchen Berg over budget problems and allegations of staff mistreatment, executive producer and series co-creator Alex Kurtzman has stepped in as showrunner for the second season. Kurtzman will also oversee the writers room. Production is well underway, with five episodes near complete, and CBS Television Studios spokesperson declared that the show remains on course for a second season in 2019 according to The Hollywood Reporter. The show has been a hit for CBS’s proprietary streaming service (see “'LOTR,' 'Trollhunters' Spin-Offs, 'Orville' & 'Discovery' Renewed, 'Darkness Visible,' 'Hitman'”), but this marks the second time a showrunner has left the series. Bryan Fuller was asked to step down before the first season debuted (see 'New 'Star Trek' Series Loses Showrunner").

Streaming giant Netflix has rescued another cancelled show. Lucifer will get a fourth season thanks to the company. There’s no word yet on how many episodes are planned (via THR). The show, which is loosely based on the DC Vertigo comic, was among several cancellations for Fox (see “The Renewed, The Cancelled, The Rebooted: 'Gotham,' 'Lost in Space,' 'iZombie,' 'The Expanse,' 'Charmed,' 'Star Wars,' and More”) as the network began a creative shift in the wake of the Disney-Fox (or Comcast-Fox; see “Comcast Outbids Disney for Fox Assets”) deal. While the show was never a ratings giant, it had a loyal following, and Netflix revived it after an enthusiastic fan campaign.

Producer extraordinaire Greg Berlanti has inked a reportedly $400 million deal to extend his contract with Warner Bros. TV another four years reports THR. Berlanti, whose contract now ends in 2024, currently has a record-breaking 14 shows on the air, including Arrow, Flash, Riverdale, and Supergirl. The deal, which is only for TV, is said to have incentives for even more shows.

American Gods has expanded its cast for the second season. Dean Winters (John Wick) has been cast as Mr. Town, Devery Jacobs (The Order) will portray Sam Black Crow, and Kahyun Kim (Shameless) has been cast as New Media, the cyberspace successor to Jillian Anderson’s more analog Media (see “'Y: The Last Man' TV Series News, 'Black Lightning' Ratings, 'The Tick' Renewed, 'Umbrella Academy' Filming, 'Snowpiercer' Greenlit, Gillian Anderson Off Geek Shows”). The season will air in 2019.

Legion is wrapping up its second season, and FX has put in an order for a third to air in 2019, according to Variety. The unorthodox superhero drama, which is based on comics by Chris Claremont and Bill Sienkiewicz (see “A Legion of 'Legion'”), added an eleventh episode to what was originally a 10-episode second season.

Syfy has ordered a pilot based on Resident Alien, a comic series from Peter Hogan and Steve Parkhouse published by Dark Horse (see “Review: 'Resident Alien Vol. 1: Welcome to Earth' TP”) .The pilot and potential series are from Universal Cable Productions, Dark Horse Entertainment, and Amblin TV. In Resident Alien, extraterrestrial Harry finds himself in a small Colorado town, where he assumes the identity of the town doctor and passes the time solving murders. Chris Sheridan (Family Guy), Mike Richardson (The Mask), Keith Goldberg (The Legend of Tarzan), Justin Falvey (The Americans), and Darryl Frank (The Americans) will executive produce.
