Production has been halted on television shows set in the Marvel Cinematic Universe as a precaution due to coronavirus.
Last week, Winter Soldier actor Sebastian Stan told his Instagram followers that the cast and crew of his upcoming series were being "sent home" from their Prague shoot.
The Falcon and the Winter Soldier had been expected to debut on Disney+ in late August, while WandaVision was scheduled for December, but it is now uncertain whether either series will arrive on time.
Disney has also suspended production on all of its live-action films, which includes Marvel's Shang-Chi and The Legend of the Ten Rings.
The director of the upcoming film, which stars Simu Liu as a martial arts superhero, has gone into self-isolation awaiting coronavirus test results.
Richard E. Grant was recently added to the cast of Loki's Disney+ series, joining Tom Hiddleston, Gugu Mbatha-Raw and Owen Wilson.
Disney Plus launches in the UK on Tuesday 24th March.
