* We Were Here: The AIDS Years in San Francisco (2011)

Filmmakers David Weissman and Bill Weber co-directed the 2001 documentary, The Cockettes, chronicling San Francisco's legendary theater troupe of hippies and drag queens, 1969 -1972. We Were Here revisits San Francisco a decade later, as its flourishing gay community is hit with an unimaginable disaster. We Were Here is the first documentary to take a deep and reflective look back at the arrival and impact of AIDS in San Francisco. It explores how the City's inhabitants were affected by, and how they responded to, that calamitous epidemic. Though a San Francisco-based story, We Were Here extends beyond San Francisco and beyond AIDS itself. It speaks to our capacity as individuals to rise to the occasion, and to the incredible power of a community coming together with love, compassion, and determination.

* Defeating the Superbugs (2012)

Across the world we are seeing the emergence of bacteria that have gone rogue. These are the superbugs, dangerous bacteria that are becoming resistant to our only defence; antibiotics.

* Defeating Cancer (2012)

Over the past year, Horizon has been behind the scenes at one of Britain's leading cancer hospitals, the Royal Marsden in London. The film follows Rosemary, Phil and Ray as they undergo remarkable new treatments - from a billion pound genetically targeted drug designed to fight a type of skin cancer, to advanced robotic surgery. We witness the breakthroughs in surgery and in scientific research that are offering new hope and helping to defeat a disease that more than one in three of us will develop at some stage of our lives.
