Certainly an interesting situation. I guess for deceased Doctor's they will go down the Tim Treloar route, I thought Angus Villiers-Stuart's impression of the 6th Doctor in Doctor's Assemble was really good. But not sure what will happen with the rest. Then again, Dr Who as a tv show came to an end so its not impossible to see the Dr Who range as we know it ending for BF. They may just end up with the Short Trips kind of narrated stuff.
I bet they will get more new Who Doctors to do BF in the next few years 🤞😊
It sounds morbid but I bet they record a lot for future releases when those Doctor's are no longer with us, pretty sure they do that with Tom.
