The creatorsof Saw and Paranormal Activity team up to reinvent the haunted-house genre for a new generation with Insidious, paying tribute to such horror classics as The Exorcist, Poltergeist and The Sixth Sense.

Rose Byrne (X-Men: First Class) and Patrick Wilson (Watchmen) believe their new house is haunted when they're son mysteriously falls into a coma  or so it seems until they realize the boy is haunted.

In this clip from Insidious, the boy's mom (Byrne) discovers a devlish hand print under her son's blankets.

Renai (Rose Byrne) and her husband Josh (Patrick Wilson) are unpacking boxes in their family’s new home when they first start to sense a sinister presence. Eerie events slowly escalate into supernatural attacks until one accident puts their son in a mysterious coma. When the family flees its ghost-ridden home and attempts to heal itself, Josh’s mother (Barbara Hershey) brings in a team of paranormal investigators led by occult expert Elise Reiner (Lin Shaye). Josh and Renai are initially skeptical, but all doubts are swept away with one terrifying discovery: It’s not the house that’s haunted. It’s their son.
