I have a couple of things to add to the 50th wish list:
1. If it is to be a series of episodes, is there any chance we could have one written or at least co-written by Terrance D1cks. If it is a true love letter to the fans, what better way to do this than to infuse it with the spirit of Classic Who!
2. Two words; Ian Chesterton. The link to the very first episode. He must be in there somewhere.
I love both of those - but they'd have to retract what Sarah Jane said about Ian and Barbara not having aged a day
Yes, that poses a little problem! But however they do it, he should be in there. I adored the Five Doctors and my only problem with it was the lack of Ian (he had Coronation St. commitments).
Also, I would like it directed by Graeme Harper.
Ian should definitely return in some form. Even if it's only recorded inserts like they did with Hartnell in The Three Doctors. And with Sarah Jane, she did say it was only a rumour. Or perhaps she was just teasing. I think it was vague enough to gloss over.
