One reason writer-director Boo Junfeng decided to tell the story of Apprentice from the perspective of an executioner's apprentice is "because stories from the prisoner's point of view have been told many times before".

He says: "I felt that maybe telling the story from a different point of view might refresh the conversation and inspire people to think from a slightly different perspective."

Here are some death penalty films from the perspective of a prisoner.

DEAD MAN WALKING (1995)

Matthew Poncelet (Sean Penn) is sentenced to die for killing a teenage couple and he asks Sister Helen Prejean (Susan Sarandon) to help him with a final appeal. It was based on the non-fiction book of the same name.

THE LIFE OF DAVID GALE (2003)

Kevin Spacey plays the titular character, a college professor and activist against capital punishment who is sentenced to death for a murder he did not commit.

LET HIM HAVE IT (1991)

A British film based on the true case of Derek Bentley (played by Christopher Eccleston), who was hanged for murder in 1953 even though he was not the one who fired the gun in the murder of a policeman.
