Do any of you remember from 1983 Tom's guest starring role in the above? I can just about - he played another Doctor - this time of a rather dubious nature called Dr Ziegler, alongside the gorgeous Patricia Hodge as Jemima Shore....
The thing I do remember well is that Tom's character drove an Austin Maxi in it, which was the same car my father had at the time!
Ring any bells?
The Doctor: I tell you, Brigadier, there's nothing to worry about! The brontosarus is large and placid!
Harry Sullivan: (to the Brigadier) This the patient, sir?
The Doctor: (looking up at Harry) And stupid!
