Peter Cushing supposedly only agreed to do this film if Roberta Tovey returned as his grand-daughter alongside him, having built up a rapport on the previous film.
A remake of the 1964 Doctor Who (1963) serial "The Dalek Invasion of Earth".
Bernard Cribbins returned to the Doctor Who franchise in 2007, starring as a recurring character, Wilfred Mott, in the fourth season of Doctor Who (2005). (However, the two Cushing movies are not considered part of the same canon as the BBC TV series.)
This sequel to Dr. Who and the Daleks (1965) was to have been followed by a third film, to be based on the 1965 TV episode "The Chase." This was never made due to disappointing box office results of the first two films and the producers thinking that "The Chase" wouldn't have made a very good movie.
This film was part-financed by the Quaker Oats Company, then-makers of the "Sugar Puffs" cereal, in return for an exclusive merchandising deal. Quaker combined with the film team in a £50,000 campaign which included 3½ million boxes of "Sugar Puffs" advertising the film, and a competition to win toy Louis Marx Daleks or the top prize, a full-size Dalek prop. Several posters for "Sugar Puffs" cereal are visible during the movie, an early (for a British film) example of product placement. Two special screenings for grocery traders were also arranged via the deal with executive producer Joe Vegoda.
André Morell was offered the role of Wyler, but could not accept because he had signed to star in the four-part Doctor Who (1963) serial, "The Massacre" with William Hartnell, which clashed with the filming dates. The role of Wyler went to Andrew Keir. Coincidentally, Morell played Professor Bernard Quatermass in the original television version of Quatermass and the Pit (1958) while Keir played him in the film remake Quatermass and the Pit (1967).
The 1960s street where the opening robbery takes place is the same one on which Wyler and Susan encounter a Dalek patrol over 180 years later (the unchanged Mitchell Real Estate premises and Harris & Son shop are prominent in both sequences). In reality this was part of the backlot at Shepperton.
During shooting in March 1966 Peter Cushing fell ill, necessitating a two week break in filming.
The rebel hideout in 2150 is prominently identified as Embankment station on the London Underground's Bakerloo and Northern Lines. There had actually been a station called Embankment once, but it was renamed in 1914; thus this was a suitable name for a fictional station. However, in 1976, 10 years after the movie was released, reality conformed to fiction when the station, now served by the Bakerloo and Northern Lines among others, was given back its original name of Embankment.
The original trailer for this film describes Ray Brooks as "The boy with the knack". Brooks starred in The Knack ...and How to Get It (1965).
Dr. Who and the Daleks (1965) co-stars Roy Castle and Jennie Linden were both unavailable when the film was green-lit, hence Ian and Barbara become Tom and Louise.
Although Milton Subotsky reported some slight misgivings over the film, believing the public's desire to see the Daleks in colour was now sated, he would come to view this as the better of the two films, attributing much of their success to art director Bill Constable.
Tom jokes about getting an OBE at the end of the film after apprehending the would-be crook. Bernard Cribbins did get an actual OBE in 2011.
The film's trailer curiously contained no direct reference to either the Daleks, Doctor Who or the TARDIS.
Despite bearing the credit "An AARU Production", this film (and its forerunner Dr. Who and the Daleks (1965)) was made entirely by Amicus. AARU received the sole production credit as part of a co-finance deal with Amicus, which felt it couldn't afford to make a movie of this scale by itself.
The Dalek saucer model resurfaced in Tigon's The Body Stealers (1969)
As well as Sugar Puffs ("The honeyest cereal of them all!") many other real-life companies and brand-names can be seen in both 1966 and 2150. These include Castrol Oil, Thomas Cook's travel, Player's and Bristol Brand cigarettes, Lyon's Maid ice cream, Heinz soup, Baron Otard cognac, Harp lager, Del Monte tinned foods, BOAC, Air India and newspapers "Daily Sketch" and "Evening News".
The film takes place in 1966 and 2150.
Stuntman Eddie Powell broke his ankle in a fall through an awning. He returned from hospital that afternoon with a cast on his leg and finished the scene. (His brother, Joe Powell, who was also doing stunt work on the film, pulled off the Black Dalek's claw during a fight scene when he was playing one of the Robomen and gets himself thrown down the bomb hole near the end of the movie. The claw magically reappeared in the next shot.)
By sheer coincidence the "rels counter" 'clockface' from the Dalek control room can be glimpsed in the parent TV series, in both the third edition of 1966's "The War Machines" and the fourth of "The Underwater Menace" the following year.
Tom's surname originated when Subotsky adapted Terry Nation's original scripts, which feature a character called David Campbell. This is why Ray Brooks' character has no surname.
Sheila Steafel was dubbed.
Philip Madoc (Brockley) went on to appear in the Doctor Who TV series. He played 4 different characters in 15 episodes.
Keith Marsh, playing Conway, only appears in the film after Wells actor Roger Avon had to leave the production and his character therefore had to be replaced.
