Some of New Zealand's most memorable screen images have come from the genre of science fiction: Bruno wandering man alone onto Eden Park in a nightie; giant slugs living under Rangitoto. From alien hunters to futuristic fuel wars to nuclear volcanoes, this collection is a showcase of film and TV that has imagined 'what if?' versions of life in the shaky isles.

Maurice Gee's classic novel about aliens running amok under Auckland has rarely gone out of print, since its debut in 1979. First adapted as a memorable 80s TV series, this movie retooling sees teenage twins Theo and Rachel stumbling across shape-shifting creatures that are hiding beneath Auckland's extinct volcanoes. American showbiz magazine Variety praised Black Sheep director Jonathan King's "solid helming", and the excellent acting of Sam Neill as the mysterious Mr Jones. Oliver Driver plays lead villain Mr Wilberforce, under four hours of make-up.

This magazine newsreel mixes buried treasure with a classic Brian Brake-shot performance piece. Opener 'The Long Poi' captures a poi dance. In 'The Buried Village' tourists examine fireballs and Māori stone carvings buried in the 1886 Tarawera eruption. The final piece showcases the talents of Kiwi pianist Richard Farrell and director Brian Brake. Brake's moody studio lighting and lively compositions frame this performance of a Chopin waltz. Farrell would die after a car accident in the United Kingdom in 1958 — the same month Brake won his first big spread in Life magazine. 

This film outlines the efforts to transform the “barren” pumice lands of the North Island’s Central Plateau into arable farmland. Once scientists discover the magic missing ingredient that will make the soil more fertile (cobalt chloride), the serious job of burning scrub, ploughing and sowing begins. The film uses a traditional 'triumph over nature' narrative, but director John Feeney makes elegant use of montage and composition. Author Maurice Shadbolt, who spent time working at the National Film Unit, regarded it as "without doubt the best film to come from the Unit".

This 1955 film looks at the “savage” geology of the North Island volcanic region, and its human settlement. Te Arawa myth introduces the steaming valleys of volcano and quake god Rūaumoko. The film then surveys geothermal activity and its exploitation by Māori and Pākehā, from cooking to heating hospital radiators. It ends with a dramatic geyser display in front of tourists. Guide Rangi cameos. It screened at the Edinburgh Film Festival, and was John Feeney’s last National Film Unit gig before directing Oscar-nominated films for the National Film Board of Canada.

In this children's sci-fi caper, an all-singing all-dancing gang of cronies led by 'evil Eva' (Nevan Rowe) holds Auckland to ransom for $5,000,000. As in Under the Mountain Auckland's volcanoes play a starring role, with Eva threatening to drop a nuclear bomb into the crater of Rangitoto. Who will save the city? A trio of intrepid kids and their DIY anti-gravity machine are on the case. Writers Ian Mune and Keith Aberdein give director Roger Donaldson (and a bevy of industry talent) plenty of goofy 70s fun to play with. Donaldson would shortly helm the acclaimed Smash Palace.

In May 1871 Auckland became a city. One hundred years later reporter Hamish Keith looks back to see how Auckland developed and ahead to where it is going. In 1971 600,000 people lived in the greater Auckland area and it was rapidly expanding. Keith notes volcanoes, tribal war, pioneers, "booze and butter" booms, problematic bridges, PI influence, cars and suburbia; and muses on Auckland’s “marching to its own drum” spirit. Anticipating Super City angst, then-Auckland mayor Sir Dove-Myer Robinson frets that sprawling unruly Auckland is a city in search of a soul.

This 1962 film about geothermal power generation begins with animated sequences telling the Māori legend of how the North Island’s volcanoes were created. Then it explores the “crazy idea” of volcanic power, and how New Zealand might harness its potential. At Wairakei, roads have collapsed and the ground can rumble: “nothing is ever quite predictable on this battleground for power”. Nearby, steam is used for heating, hangi, bathing, and … growing pineapples. The animation was handled by Mike Walker (later producer of Kingi’s Story), of Levin-based Morrow Productions.

From a pre-Mythbusters era when science didn’t need explosions to merit primetime Saturday night screening, but after NZBC's blackboards and pointers, this series took a current affairs approach to reporting contemporary scientific research. Produced in Christchurch’s Studio 4, it was presented by Ken Ellis; Allanah James was a long-time reporter. Subjects ranged from volcanoes, underwater welding, talking lifts, STDs, mutant spiders, mussel extracts, and nude rats to the mysteries of tuatara and concert hall acoustics. The series was succeeded by Fast Forward.

Classic sci-fi TV series Under the Mountain follows the adventures of redheaded twins with psychic powers — Rachel and Theo — on their Auckland summer holiday. They meet the mysterious Mr Jones, an alien emissary who enlists them in the battle against the evil Wilberforces, who are plotting planetary destruction. Adapted from the Maurice Gee novel, the series' fx left their slimy imprint on a generation of NZ kids, haunted by the transmogrifying Wilberforces, who changed from humans into giant slugs slithering underneath Auckland’s volcanoes.
