The Macra Does Exist.

TV Although I didn't enjoy everything about animated version of Doctor Who's The Macra Terror, I understood that such things as the scene omissions and the way the scenes often stray wildly from the telesnaps were as a result of the production schedule and budget.

This brilliant making of explains just how difficult it is to create these animations, featuring short essays by most of the key creatives.

 Here's Charles Norton on thinking through how the project would even work:

"... when Paul first started talking about tackling another of these projects around Christmas 2017, we all had certain reservations. A project of this scale really needed a full year of production time or as close to it as reasonably possible. It ideally needed to have the resources to cover an all-under-one-roof team of character animators. We needed dedicated production and studio managers, so that the director could really just concentrate on actually directing and not everything else. This is far closer to how such shows are run in the States. The way Warner Brothers make their straight-to-DVD Batman animations, for instance. The idea there is to sub-contract out much of the heavy-lifting 'grunt-work' of character animation, leaving your core creative team to concentrate primarily on story direction and design."

In any case, it's better than whatever was going on in the Reign of Terror animation.
