Sadly, Steven Moffat didn't get his wish. The celebration of 50 years of Doctor Who contained no references to the strange spin-off Doctor played by Peter Cushing in the '60s. However, Moffat's words do possibly clear up one of the great faux pas in the show's history.
First, some background. Peter Cushing played a version of The Doctor in two films in the '60s. These were Dr. Who and The Daleks and Daleks' Invasion Earth 2150 A.D. The films, which were actually the first Doctor Who to be colorized and the first presented in widescreen as well, were meant to capitalize on the huge popularity of the Daleks and possibly make some inroads in America, where Doctor Who was still completely unknown.
The first film was more or less a remake of the second William Hartnell serial, "The Daleks." At this point it is impossible to overstate how popular the Daleks were, in many ways overshadowing the rest of the show entirely. Terry Nation, the creator of the Daleks, agreed to license his most famous creations to be adapted as long as longtime script editor David Whitaker (author of the novelization of "The Daleks") was hired to adapt.
