Top 25 made up commercials in SF movies

20: Brazil (1985) - Sam Lowry drives up to happiness.
The contrast between the idylls of architects and the grim reality of what their housing estates become is also played with in the Back To The Future trilogy, but here director Terry Gilliam paints an immediate and dispiriting contrast between the dream and the reality...

19: Scanners (1981) - 'Ephemorol' magazine ad.
I'm unable to find out who the graphic artist was behind this extraordinary recreation of late-40s/early 50s magazine ad artwork in David Cronenberg's grisly thriller. Ephemerol is the fictional tranquiliser for expectant mothers that turns out to have created a race of telekinetic warriors called 'scanners', and the quality of this ad really 'sells' the idea...

18: Blade Runner (1982) - 'A new life Off-World!'.
The travelling nature of this commercial uber-blimp both harks back to the days of the Zeppelin and looks presciently forward to the mobile hoardings that ride the roads of modern city centres today. Though the ad by itself does not entirely explain the evacuation of Earth (a confusing aspect, as the city in Ridley Scott's SF-Noir is so overcrowded), the explanation is completed at Bryant's briefing and J. F. Sebastian's explanation to Pris as to why he is still on Earth. In any case, the Blade Runner blimp turns out to be right on time...

17: Children Of Men (2006) - Video ads, London 2027.
Alfonso Cuarón's adaptation of P.D. James' 'uterine apocalypse' novel finds a very recognisable modern London lightly retro-fitted, with more advanced (or somehow more affordable) video-technology grafted onto the familiar advertising spaces of London buses. Flying cars would have been daft, but the odd unfamiliar curve might have helped to sell the future metropolis.

16: The 6th Day (2000) - 'Repet' TV spot.
Arnie faces the problem of many a dad when his daughter's beloved dog bites the dust while she is away. A substitute goldfish you could maybe get away with, but only advanced genetic engineering can actually bring the pooch back from the dead. The idea of grafting custom DNA onto generic host templates also seems to be the technology at use in the 'Janus project' at the end of Judge Dredd (1995).
