A wholly innovative, original, and vital history lesson, with pioneering animation, Waltz With Bashir delivers its message about the Middle East in a mesmerizing fashion. Director Ari Folman's animated quasi-documentary follows the filmmaker's emotional attempt to decipher the horrors that unfolded one night in September of 1982, when Christian militia members massacred more than 3,000 Palestinian refugees in the heart of Beirut as Israeli soldiers surrounded the area". Folman was one of those soldiers, but nearly 20 years after the fact, his memories of that night remain particularly hazy. After hearing an old friend recall a vivid nightmare in which he is pursued by 26 ferocious dogs, Folman and his friend conclude that the dream must somehow relate to that fateful mission during the first Lebanon War. When Folman realizes that his recollections regarding that period in his life seem to have somehow been wiped clean, he travels the world to interview old friends and fellow soldiers from the war. Later, as Folman's memory begins to emerge in a series of surreal images, he begins to uncover a truth about himself that will haunt him for the rest of his days.

In 2000, Bill and Hillary Clinton owed millions of dollars in legal debt. Since then, they’ve earned over $130 million. Where did the money come from? Most people assume that the Clintons amassed their wealth through lucrative book deals and high-six figure fees for speaking gigs. Now, Peter Schweizer shows who is really behind those enormous payments. He detailed patterns of official corruption in Washington that led to congressional resignations and new ethics laws. He follows the Clinton money trail, revealing the connection between their personal fortune, their “close personal friends,” the Clinton Foundation, foreign nations, and some of the highest ranks of government.

In 1985, two adventurous young mountaineers, Joe Simpson and Simon Yates, set off to climb the treacherous west face of the Siula Grande in the Peruvian Andes. They were experienced climbers, and climbed "Alpine-style," climbing the mountain in "one great push," without setting up ropes or base camps ahead of time. After dealing with a snowstorm and some dangerous climbing over powder formations, they reached the summit (about 21,000 feet) on the third day. The climb down proved to be far more difficult. Simpson fell and broke his leg badly. Yates decided to try to lower Simpson down the mountain, one 300-foot section of rope at a time. The climbers had run out of gas to melt snow, so they couldn't risk stopping as night came, and a violent snowstorm began. Their plodding, painful journey hit a snag when Yates inadvertently lowered Simpson over the edge of a cliff. In the storm, the men couldn't hear each other's cries, and, Yates, uncertain as to Simpson's position, and gradually sliding down the slope himself, decided to cut the rope that connected them, sending Simpson plummeting to certain death. Miraculously, Simpson survived the fall, and was faced with the prospect of getting off the mountain alone with no food, no water, and a broken leg. In Touching the Void, filmmaker Kevin Macdonald (One Day in September) tells their story, based on Simpson's book, using contemporary interviews with the two men, and a reenactment of their climb and descent, featuring Brendan Mackey as Simpson and Nicholas Aaron as Yates
