A tribute to the spirit and humanity of people who are physically different from the average: very tall and very large men and women, a bearded woman and her long-time husband, Siamese twins joined at the midsection, and several little people including actor Billy Barty. We meet some at Gibsonton, Florida, where carnival folk winter. They talk about their lives and accomplishments. The camera also goes on the road to visit a grandfather with a distinctive face, a legless mechanic from Kentucky on a second honeymoon in LA, a marathon runner and motivational speaker who has no feet, a karate student with partial limbs, and an armless, down-to-earth mom in Texas.

This impressionistic portrait of the 1964 Tokyo Summer Olympics pays as much attention to the crowds and workers as it does to the actual competitive events. Highlights include an epic pole-vaulting match between West Germany and America, and the final marathon race through Tokyo’s streets. Two athletes are highlighted: Ethiopian marathon runner Abebe Bikila, who receives his second gold medal, and runner Ahamed Isa from Chad, representing a country younger than he is.

As the unabashed cradle of Hollywood superficiality and smoggy urban sprawl, Los Angeles has long been condemned as a cultural wasteland.

Pablo needs to stop smoking. Why? Because his wife, family and doctor say he should. But Pablo is a stubborn man. He has worked in the mercury mines of Almadén, Spain, risking his life daily. He has had five severe heart attacks and smoked 20 Winston’s a day since he was 12. Now in his seventies, Pablo spends most of his day in front of the TV, surrounded by a cloud of smoke, with his back turned firmly towards a village that has lived through better times. Pablo represents the last generation of Almadén mercury miners, an age-old profession with over 2,000 years of history. Through a straightforward depiction of life’s everyday moments, Pablo’s Winter explores the decay of the local mining culture, but above all, pays homage to its real protagonists: the miners and their families.

Hippos and crocs have lived side by side for millennia, but are they cozy bedfellows or arch-enemies? One is a hefty herbivore, the other is the most successful freshwater predator on the planet, so how do they manage to survive together in the same habitat? They each have a unique arsenal of attributes honed by centuries of evolution; muscle power, bite force and ferocious dentition give them the edge in their environment. But once a year, their peaceful semi-aquatic existence turns into a battle for survival.

Is it possible to call a surfboard the best in the world? Is it possible to call a shaper the best in the world? Each year we invite 12 of the world’s best shapers to shape a clear and unmarked surfboard for an unknown surfer of specified height and weight. Neither the shaper nor surfer know who the other is in surfing’s ultimate double-blind taste test. This year, we invited the six most winning shapers of the event as well as former test pilots Dane Reynolds, Mick Fanning and Jordy Smith to South Africa. Dealing with the ocean and wind, mother nature is typically a surfer’s biggest wildcard threat to a project. This year, however, we had even more surprises than we could have bargained for. But, we did find our winner.
