A Canadian filmmaker is breathing new hope into the decades-old murder case involving the group known as the West Memphis Three who became a cause célèbre.

The men, who were teenagers when they were convicted of the brutal murder of three young boys, were released two years ago after serving 20 years in prison for crimes they insist they didn't commit.

The new movie Devil`s Knot directed by Atom Egoyan, which debuted at the 2013 Toronto International Film Festival, is one of many films made in an attempt to further understand the murders.

CBC News reporter Nil Köksal talks to James Baldwin of the West Memphis Three.
