The sci-fi epic has added a trio of new cast members to its upcoming season, which has officially begun production.

Netflix is staging a Game of Thrones reunion. Alfie Allen has joined the cast of 3 Body Problem, reuniting TV’s erstwhile Theon Greyjoy with Thrones creators David Benioff and D.B. Weiss. Character details are being kept under wraps.

Netflix's hit sci-fi drama 3 Body Problem was renewed for a second and third season in 2024, a little while after the first season premiered on the streamer. The summer has seen production plans ramp up significantly in recent weeks with new characters being cast and the potential of the story heading to a new location.
