No retconning on my part. I have always viewed those other faces as anything but those of Morbius and have trouble how anybody could consider them the Doctor since it had already been established that Hartnell was the first.
Well, without be rude enough to ask your age, I suspect it does depend on how old you were in 1976.
I don't think age has much to do about how the scene was viewed, like many others I thought those were past faces of Morbius not the Doctor. Of course in Mawdryn Undead the Doctor said he had more lives left, so I guess you either go by behind the scenes talk or what's onscreen.
Sorry, I could have made my point clearer: I meant that if you first saw Morbius in January 1976, then you tend to view it differently from someone who's watching it after Deadly Assassin and already knows about the 12 regenerations thing from all the mentions in PR material, reference books and DWM.
BTW: My sister (who also saw it back on first transmission) says for she thought then that the other faces were Hartnell getting younger...
