AARU productions was formed by another film-maker, Amicus, to create a cinematic version of the BBC's Doctor Who - this feature was the result.
Based on the seven-part TV serial The Daleks (aka. The Mutants), this rendition was the programme's first ever spin-off. The film was also the first Doctor Who adventure made in colour (only used on the TV series from 1970) and widescreen (introduced with the 2005 revival).
Dr Who and the Daleks was scripted by (TV writers) Terry Nation,
David Whitaker, (the producers) Max Rosenborg, and Milton Subotsky, and directed by Gordon Flemyng.
The cast was headed by horror film legend, Peter Cushing, as the human inventor 'Dr. Who'. Jennie Linden and Roberta Tovey played his granddaughters, Barbara and Susan, whilst Carry On star, Roy Castle, was the hapless Ian Chesterton.
Further connections to the parent TV series are as follows:

- Tovey had an uncredited role in The Blood on Satan's Claw (1971) which also featured Wendy Padbury and Anthony Ainley - in Runaway Railway (1965) she starred opposite Pertwee, and her father, George Tovey, was the Poacher in Pyramids of Mars
