A mesmerising documentary thriller with a killer whale at its centre, Blackfish is the first film since Grizzly Man to show how nature can get revenge on man when pushed to its limits.

Blackfish tells the story of Tilikum, a performing killer whale that killed several people while in captivity. Along the way, director-producer Gabriela Cowperthwaite compiles shocking footage and emotional interviews to explore the creature's extraordinary nature, the species' cruel treatment in captivity, the lives and losses of the trainers and the pressures brought to bear by the mulit-billion dollar sea-park industry.

This emotionally wrenching, tautly structured story challenges us to consider our relationship to nature and reveals how little we humans have learned from these highly intelligent and enormously sentient fellow mammals.

Documentary that makes use of unprecedented access to follow life in the New York Times newsroom for a year. The New York Times is arguably the most important newspaper in the world; it is certainly one of the best read and most influential newspapers in the United States. Filmmaker Andrew Rossi was granted rare access to the internal workings of the newspaper for this documentary, where he captures the frantic nature of professional journalism as stories erupt and advances in technology continually force the paper to adapt. In particular, the story of crusading journalist David Carr is picked up. Carr attends closely to the threat of social media and internet technology to the kind of professional, newsroom-based journalism of the New York Times and offers a staunch defence of his paper and the print media it represents.

In 1962 four young men John Lennon, Paul McCartney, George Harrison and Ringo Starr came together to form the 20th century musical phenomenon known as The Beatles.

The band stormed Europe in 1963, and, in 1964, they conquered America. Their groundbreaking world tours changed global youth culture forever and, arguably, invented mass entertainment as we know it today. All the while, the group were composing and recording a series of extraordinarily successful singles and albums. However the relentless pressure of such unprecedented fame, that in 1966 became uncontrollable turmoil, led to the decision to stop touring. In the ensuing years The Beatles were then free to focus on a series of albums that changed the face of recorded music.

Master storyteller and Oscar winner, Ron Howard, explores this incredible journey in his own unique way: How did The Beatles do this? How did they cope with all the fame and pressure? How did they not only survive, but go on to revolutionise popular music?

With original interviews, footage, staggering live performances, and the intimate study of character that Ron Howard is known for, he puts us right inside this extraordinary adventure, answering the question everyone always wants to know: What was it like to be there?!!
