Behind the scenes Edit
A series for this character was announced before her first story had even been released. Producer David Richardson was quick to clarify that he "did not see it as a Doctor Who spin-off. It's its own thing. It's not set in the Doctor Who world at all." However, with the release of the third series of Vienna in 2016, Big Finish released a promotional article on their website that compared the Vienna series to various Doctor Who spin-offs such as Gallifrey, Charlotte Pollard, Jago & Litefoot, and Counter-Measures.
Moreover, in a behind-the-scenes interview included with the 2018 release Vienna: Retribution, Chase Masterson herself referred to Vienna as being a Doctor Who spin-off.
