Some of this year's most talked about talent open up about the challenges and triumphs of creating critically acclaimed series and performances.

New York, 1980. Three complete strangers accidentally discover that they're identical triplets, separated at birth. The 19-year-olds' joyous reunion catapults them to international fame, but also unlocks an extraordinary and disturbing secret that goes beyond their own lives – and could transform our understanding of human nature forever.

Every year in Britain, more than 600 people commit murder. The majority of these killers will eventually be sent to Gartree Prison in Leicester, which is home to Europe's largest population of life-sentenced prisoners. A brand new Cutting Edge documentary filmed over six months at HMP Gartree now provides an unprecedented insight into the lives of convicted killers facing a lifetime behind bars. These men will die in prison unless they can convince the authorities they have changed and are no longer a risk to society. With unique access to Gartree's cells, landings, segregation unit and visiting rooms, Lifers explores the everyday realities of prison life for those convicted of murder. The documentary examines the psychological impact of killing, following prisoners as they try to come to terms with what they've done, with varying degrees of remorse and contrition.

This documentary explores the phenomenon of a one punch kill, by examining three different assaults: single hits with dire consequences, often in innocuous locations and circumstances

Inspired by the documentary "Three Identical Strangers," Michele Mordkoff and Allison Kanter discover they are twins and have an emotional reunion on camera.
