This two part documentary traces the identical twins’ rise and fall, exploring their control of London’s East End underworld during the 1950s and 1960s and the turbulent relationship between them. Archive footage, expert interviews and first hand accounts examine the men behind the mythology and the crimes concealed beneath their carefully cultivated image.

Now working as a police dispatcher, Ian has never accepted that Maggie may be gone forever. When he answers a distress call from a teenage girl and becomes convinced the voice belongs to his missing daughter, he begins a relentless search that could either reunite his broken family or destroy what remains of it.

Set and filmed in Victoria, the six episode series also stars Maxine Peake, Brendan Cowell, Daniel Henshall and Zahra Newman.

SBS On Demand | Free | Precious Metal: A Love Story

What is it about a car that can inspire a lifelong obsession? In this Australian documentary series, Voyager frontman Danny Estrin meets people whose vehicles mean far more to them than simply getting from one place to another.

From a much loved Fiat 500 to rare classics, Estrin discovers the stories behind the cars and the passionate owners who see them as symbols of freedom, identity and escape. Even viewers who cannot tell what is under the bonnet may find themselves drawn into the human stories behind these prized machines.

Moving between Kaczynski’s early life and the later investigation, the two part series explores his path from isolated student to the infamous Unabomber.

Bette Midler, Goldie Hawn and Diane Keaton join forces in this much loved 1996 comedy about three former school friends who reunite at the funeral of a classmate.
