The Star Beast: Behind the Scenes (documentary)

 was a documentary released on YouTube on 25 November 2023 following the broadcast of The Star Beast. Covering the production of that story, it included many interviews with cast and crew. It was completely separate and in addition to Doctor Who: Unleashed, giving a more in-depth look at other parts of the production process. Made by the same BTS team, the most apparent difference is the lack of Steffan Powell presenting.
