James McAvoy and James Watkins on the set of Speak No Evil
 
 
The thriller Speak No Evil opens in theaters on September 13. James McAvoy and Mackenzie Davis star in the tense story of a trip that goes horribly wrong.
 
“This film explores the horrors of social interaction,” says writer/director James Watkins. “The world is so complicated now. What are the rules?”
 
In the exclusive video below, Watkins walks us through a scene that marks a turning point in the movie. “This is the point where the characters are getting to the line of what’s acceptable – and then crossing that line.”
