The first trailer for true-story crime drama "Devil's Knot" has been released, giving a look at Atom Egoyan's take on the infamous West Memphis Three. It shows the small town and religious community of West Memphis, Arkansas left shaken by the brutal murders of three 8-year-old boys, AceShowbiz said.

Due to the violent and gruesome nature of the killings, some residents believed that a satanic cult was responsible for the crime. "The Amazing Spider-Man 2" star Dane DeHaan plays one of three teenage suspects who were convicted despite a lack of evidence.

Based on Mara Leveritt's 1993 book, the film has been premiered at the Toronto International Film Festival but hasn't got a U.S. theatrical release date yet. Reese Witherspoon stars as one of the victims' mother, and Colin Firth as private investigator Ron Lax.
