This weekend marks the third year for the British Animation Film Festival, taking place in London's Leicester Square. One of festival's best films is Sara Kenney's Angels And Ghosts, a gripping animated adventure exploring the potent themes of mental health and family bonds.

Director Sarah Kenney has first-hand experience of knowing people who have had psychotic episodes and wanted to find a way to tell a story which reflects both the patent and family perspective. Oscar-nominee Samantha Morton narrates in a monologue the emotive tale of Amber, a young woman on a quest to find her absent brothers.

Fresh from winning the Best Animation prize at the 2014 St Alban's Film Festival, animation director Simon Armstrong of Ticktockrobot was on hand to give Digital Arts a behind-the-scenes tour of the highly imaginative world, characters and production of Angels And Ghosts.
