Coherence is currently playing at the Edinburgh Film Festival and is a small independent sci-fi thriller.  It was directed, in his first feature film, by James Ward Byrkit, who is best known for his role as a writer on Rango.  Shot inside his own home, he decided against the use of a traditional script, instead just mapping out the major plot points.  This allowed the actors to improvise and brings a realist feel to the dialogue.
