Jac Schaeffer Developing New Stargate Series for Amazon MGM, Report Says

The hiring of a high‑profile Marvel showrunner signals Amazon MGM’s renewed effort to relaunch the long-running sci‑fi franchise.

Overview

  • Variety reported that Jac Schaeffer is developing a new Stargate television series under her overall deal with Amazon MGM, and representatives for Amazon and Schaeffer declined to comment.
  • Sources told Variety a writers’ room is expected to open soon, placing the project in early-stage development rather than in production or casting.
  • Joby Harold and Tory Tunnell of Safehouse Pictures are reported to be attached as executive producers alongside Schaeffer.
  • The report frames this as Amazon’s second attempt to reboot Stargate after a previously reported Martin Gero version did not move forward, showing the studio is restarting development with new creative leadership.
  • Schaeffer’s credits include WandaVision and the Agatha All Along spinoff, and Amazon’s move suggests it wants a voice that can balance franchise lore with stories accessible to new viewers; Stargate began with the 1994 film and later expanded into series such as Stargate SG-1 and Stargate Atlantis.
