Good Boy tells the story of a dog that moves into a rural home, and becomes aware of supernatural forces threatening his owner.

IFC has expanded the theatrical release of the upcoming horror film "Good Boy" from limited to full wide release in response to the fervor over the movie's trailer -- more than one million people viewed the clip since its debut on Aug.

The news comes in the wake of the first trailer for the movie barking up over 1 million views on YouTube within four days. Good Boy stars Indy, the real-life pet of writer-director Ben Leonberg, as a dog (also named Indy) who tries to warn his owner (Shane Jensen) of evil supernatural forces encroaching on their rural farmhouse.
