Oh, seeing that colourised photo of Wendy Padbury, Patrick Troughton, and Frazer Hines is very cool!
As I just wrote in another comment, it's the runtime I'm worried about. The Daleks was shorter than The war games in their original playing time, and that got mangled in last year's "feature-length" colourisation.
Anyway, I think 200-250 minutes is a perfectly acceptable length for a feature these days? 😛
