Those with a fear of heights be warned, this is not the programme for you. 'Don't Look Down is a documentary following urban free climbers. These are people who go around climbing cranes and buildings and what not, WITHOUT any ropes or safety equipment. The mad yokes. The film focuses on 23-year-old James Kingston who is big into it, and goes to Russia to meet one of the world's best. This one will have us all grabbing on to our couches praying they don't fall.
