Dr. Who and the Daleks

This 1965 film cashed in on the craze of Dalekmania by adapting the Doctor Who episode "The Daleks" into a cinema spectacle. It featured the Daleks - IN COLOUR! - battling against Peter Cushing as Dr Who.

It was followed a year later by Daleks' Invasion Earth: 2150 AD.

Tropes used in this film:

 * Alternate Continuity: Let us count the ways!
 * The character of the Time Lord known as The Doctor has become a human scientist called Dr. Who.
 * Susan and Barbara are both his granddaughters (with the surname Who, to boot).
 * Ian is Barbara's boyfriend, neither of them is a teacher, and both are teenagers.
 * Susan is a little girl of about twelve.
 * Dr. Who's ship is known as TARDIS (note the lack of the definite article).
 * TARDIS is still a police box that is Bigger on the Inside (somehow), but its interior consists of only one room, and it's built very haphazardly. There's no hexagonal console, time rotor, or roundels--there are many random buttons, wires, and switches, and a single lever is all that controls the space/time travel mechanism. Also, no vworp noise.
 * Canon Immigrant/Development Gag: The Daleks in this film were supposed to have flamethrowers, which were scrapped for the infamous fog cannons. However, flamethrowers were included with the Daleks in regular canon, in "The Daleks' Master Plan."
 * Compressed Adaptation: From seven 25-minute episodes (175 minutes total) to one 79-minute film.
 * Sequel Hook: At the end, our heroes try to get back to London, but end up in the middle of an ancient Roman battle.
 * Zeerust: The Daleks' colourful fortress, big time. The Dalek control room even has lava lamps, which probably still seemed incredibly futuristic in 1965.
