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.

In the third episode of Johnstone’s Journey, broadcaster Ian Johnstone meets three generations of the Wendelken family. The episode is framed around an interview with matriarch Elsie, 85, then living in Timaru — her daughter Rae and grandson Ivan farm nearby. Son John is a public servant in Wellington; granddaughter Anne is a mother in suburban Wellington. Topics span from world wars, depression, farming and inflation, to shifting values. Says Elsie: “There are two things that have been left completely out of today’s young people: one is obedience, and the other is discipline.”

In this feisty late 1976 The Friday Conference interview, host Gordon Dryden holds Prime Minister Muldoon to account over his 1975 election pledges. Dryden challenges Muldoon’s touting of freedom (amidst price freezes, wage controls and an All Blacks tour to apartheid South Africa), and the PM's description of himself as a liberal (with heated talk about insults traded during the Colin Moyle affair). Dryden evokes the spectre of the McCarthy era, and a pugnacious Muldoon invokes “the ordinary bloke”. Muldoon later refused to be interviewed by Dryden again for the show. 

The tagline runs: "The story of unemployment in New Zealand" and In A Land of Plenty is an exploration of just that; it takes as its starting point the consensus from The Depression onwards that Godzone economic policy should focus on achieving full employment, and explores how this was radically shifted by the 1984 Labour government. Director Alister Barry's perspective is clear, as he trains a humanist lens on ‘Rogernomics' to argue for the policy's negative effects on society, "as a new poverty-stricken underclass developed".

This 70s current affairs show does a cost benefit analysis of Trade Minister Warren Freer’s Maximum Retail Price scheme (MRP), which capped retail prices. Drawn from an era of economic theory poles that was apart from the market deregulation of the 80s, the investigation sets out to poll opinion in supermarket aisles, a grocery in Glenorchy, and factory floors (Faggs coffee, Cadbury chocolate). The checkouts are a battlefield between red tape and free range retail. The early animated sequence by Bob Stenhouse marked an early use of animation in a local TV documentary. 

This four-part series from 1996 presents the game of rugby as a mirror for New Zealand social history. Written by Finlay Macdonald, it sets out to explain how rugby became such an intrinsic part of New Zealand's identity. Each episode visits iconic paddocks (from schools to stadiums) and players (from amateurs Nepia, Meads, and Shelford, to professional star Lomu); and observers muse on the influence of the inflated pig's bladder on Kiwi culture, including historian Jock Phillips, writer Ian Cross and journalist TP Mclean.

For the 2009 final of this iconic Kiwi game show, Taupō — "the spiritual home of trout", according to host Mikey Havoc — takes on Whakatāne. Civic pride is, as always, on the line. The crowd at Christchurch's Jellie Park are amped as two fit and motivated teams fling their bodies against a giant, inflatable obstacle course and compete in rounds with names like Rolling Road and Roller Derby. Hosts Mikey Havoc, Marc Ellis ( whose voice is taking a beating) and Hayley Holt quiz the teams poolside, while commentator Nathan Rarere enjoys skewering a long list of sporting cliches. 

Taika Waititi's blockbuster second movie revolves around an imaginative 11-year-old East Coast boy (James Rolleston) trying to make sense of his world — and the return of his just-out-of-jail father (Waititi). Intended as a "painful comedy of growing up", Boy mixes poignancy with trademark whimsy and visual inventiveness. The film was shot in the Bay of Plenty area where Waititi partly grew up. A winner in its section at the 2010 Berlin Film Festival, Boy soon became the most successful local release on its home soil (at least until the arrival of Waititi's 2016 hit Hunt for the Wilderpeople).

Smith (Sam Neill, in his breakthrough screen role) is devastated when his wife runs off with his best friend Bullen (Ian Mune). Smith escapes to the Coromandel. Meanwhile, the government enlists an anti-terrorist force to crack down on its opponents. Bullen, now a guerrilla, asks Smith to join the revolution. Directed by Roger Donaldson, this adaptation of CK Stead's novel Smith's Dream heralded a new wave of Kiwi cinema; it was one of the only local films of the 1970s to win a big local audience. This excerpt includes a much talked about scene: a baton charge by government forces.

A talkback radio operator (Lucy Sheehan) is forced to stand in for the regular host when he walks out because of a personal crisis. In between trying to answer calls, organize a replacement and discuss odd topics with a succession of callers, the flustered operator makes a surprising connection with another lost soul. Auckland's urban soul is captured with distinctive assurance in this neglected 48-minute drama from director Alison Maclean — who wrote the script with Geoff Chapple.
