Director S.J. Clarkson's "Star Trek 4" has been shelved, at least that's what Deadline is reporting in their annual assessment of upcoming Paramount projects for 2019:
"Clarkson was the first female director to be tapped to direct a Star Trek movie when she was hired to helm the fourth feature in the current series. That project has since been shelved."
Casting reportedly "got bad," according to numerous sources, with some specifically pointing the finger to the "abnormally high" salaries demanded by stars Chris Pine and Chris Hemsworth. “Jessica Jones” director Clarkson had signed on to helm the the film, based on a script by uncredited “Star Trek: Beyond” writers J.D. Payne and Patrick McKay. The film was rumored to see Hemsworth’s George Kirk (Capt. Kirk’s dad, who famously died in the opening minutes of Abram’s 2009 reboot) returning to the franchise alongside the NuTrek cast of Chris Pine, Zachary Quinto, Zoe Saldana, Simon Pegg, Karl Urban, and John Cho.
