I mentioned in my review of The Sea Devils that the DVD included a complete book in PDF format. Well, I just had a look and I’m really happy about it! It’s called The Making of Doctor Who, and I actually had it when I was a kid! Now I haven’t seen the book in, I dunno, must be well over 20 years, but there were bits I remembered – it has documents allegedly from the Time Lord archives about the Doctor’s trial, memos from the Brigadier, and loads of background on the history and development of the series over its first nine years.
If you have the DVD, make sure you put it in your computer and have a look at the extra stuff. The old Radio Times listings are worth a quick look, too.
