After making big-budget movies like The Last Airbender and After Earth over the past few years, director M. Night Shyamalan returned to his thriller roots last year with The Visit. The filmmaker teamed up with producer Jason Blum for this low-budget story that features largely unknown actors. With The Visit arriving on Blu-ray and DVD today from Universal Pictures Home Entertainment, we have an exclusive preview where the filmmaker discusses his casting approach.

The director addresses the notion that 80% of a director's job is casting, revealing that his first decision was to only cast actors who weren't "super-famous." He talked about his approach to casting The Visit, stating that he wouldn't let anyone be around him while he was making his decisions, and that he thinks the result is "a perfect constellation of actors." The filmmaker adds that stars such as Olivia DeJonge, Ed Oxenbould, Kathryn Hahn, Deanna Dunagan and Peter McRobbie were chosen with purity.
