10 Times Doctor Who Made Obvious Mistakes
5. Shooting Almost An Entire Doctor Who Story On Green Screen
Now that Doctor Who is about to be a global smash on Disney+, it has access to the virtual screens used by productions such as The Mandalorian. It's speculated that this technology will be used to realize Ncuti Gatwa's "impossible" new TARDIS set, but that remains to be seen.
Whatever the truth, and whatever the results, it can't be any worse than what fans got with the 1978 serial Underworld.
Underworld has the dubious honour of being the Tom Baker serial that is the worst regarded. One of the reasons for this, aside from the naff sci-fi retelling of Greek mythology, is that many of the locations are realized using Colour Separation Overlay. Essentially, Tom Baker, Louise Jameson, and the guest cast performed their scenes in front of a big green sheet.
This wasn't some bold attempt at pushing Doctor Who into the future of virtual sets, however. The construction of the Minyan ship set, one of the few physical locations in the story, was so expensive that they had to cut costs. So, 1970s Doctor Who was forced to push its love of green screen to the very limit.
