Doctor Who Meets Mad Max: Ether Overdrive was an independent film made in Australia in 1988 that combined both the Doctor Who and Mad Max media properties. Shepherded into production by their respective companies without either creative team, the movie did poorly upon limited release. Australia's Herald Sun newspaper described the film as "pure, unadulterated agony ... excruciating."
“Doctor Who” is a human scientist from the present day who travels into the far future in his “Time Ford” automobile, which may have been influenced by the hit film Back to the Future (released only four years previously). In the far future, Doctor Who discovers that Daleks from outer space had crash-landed many years ago and enslaved humanity to power their ramshackle technology. Doctor Who decides to travel back to “the future’s past” to a time period still many years in the future from the present day, hoping to find a way to change time and defeat the Daleks before they took over the world. He meets Mad Max who’s fighting the encamped Daleks around their recently-wrecked spaceship and the two decide to work together. They eventually use Doctor Who’s Time Ford as bait to draw the Daleks out into a high-speed chase along an empty desert highway, who pursue in hopes of claiming Doctor Who's "ether overdrive", a nearly unlimited power source that Doctor Who had invented to run his car. Mad Max drives the Time Ford while Doctor Who drops some “magnetic traps” along the highway that makes the Daleks explode.
Because the Daleks had crashed on Earth and lost their technology, they had to rebuild their armored shells with spare parts in a cave, so they don’t appear like the traditional Daleks from the television programme. Neither McCoy, who was cast as The Doctor at the time, nor Mel Gibson who had portrayed Mad Max in the previous films reprised their roles, which went instead to some New Zealand actors. Actress Janet Fielder who had played Tegan Jovankoff on Doctor Who a few years previously was given a part, only to see most of her scenes cut in favor of a small feral mutant child named “Adroc” that Doctor Who and Mad Max befriended, who bore no relation to the Doctor Who character Adric. Much like the Peter Crushing Doctor Who movies from the 1960s, most Doctor Who fans generally don’t consider the film to be canon.
The movie is most remembered today only for a popular dance music single that was released with the film. None of the actors appeared in its music video, but a few action sequences and props from the film were used to fill out the screne time.

Hearing the Doctor speak with an Australian accent was just wrong though.
