8. Focus On A Small Group, But Give Everyone Their Moment
I think practically, most of the action and focus should be on Doctors 8-11, and possibly 5 to an extent. 8 huge egos in a massive ensemble piece is going to be hard to do, and thats without plot and other characters. We need the focus to be on a few of The Doctors, but give everyone their dues. For example, every character, including Nick Fury, Maria Hill, Agent Coulson and Loki has their memorable moment(s) to shine that the fans love, enough though they were not the main focus. And here, every Doctor, however much focus is put on them, gets their moment that makes their fan glad they were brought back. The most important rule, I think is no companions. Not one present companion, no present companions. This is, likely, called The Eleven Doctors, not The Eleven Companions. From a dramatic point of view, The Doctors only company is himself, and he has no one to hold him back, or advise him. Hes out for himself with no help but himself. Also, it will be busy enough, and we dont want it bloated. Sorry, but thats what I think anyway. The elephant in the TARDIS, of course, is the first three. Sadly, these marvellous actors are no longer with us. But it would be an insult to use them in archive footage, or as 3D floating heads, or as soundclips. They might as well not be in it if that is how they are treated. And its not a multi-doctor special without them. They can be just as important and have their moment to shine. Perhaps as holograms, or fleeting appearances before vanishing as they are too far back in The Doctors personal timestream. But then wibbly-wobbly-timey-wimey! Aware of future events, they can plan. They train an prepare themselves. The Doctor knows how to save the day as The Eleventh because he saw how to as The First. A wonderful narrative device, basically making the Doctors no longer with us the true heroes of the piece. I cant think of anything more awesome and respectful than that!
