After delivering a seemingly out-and-out ending, "The Cabin in the Woods" may have more story to tell, according to the film's co-writer Joss Whedon.

Drew Goddard ("Cloverfield") directed and co-wrote the Lionsgate film, which ruthlessly twists horror genre mechanics with its unconventional story.

But this may be just the beginning of this film's surprising tale.

"I grew up with comics where writers always thought, 'How can we bring this guy back, or that guy back?,'" Whedon said in an interview with Cinema Blend. "And Drew and I, we have no artistic integrity.

"We also built that world so grandly in our minds that we often do go, 'Wouldn’t it be great if we could do the bit where …' There’s definitely more to be told in that story."

The film follows a group of friends who visit a quaint cabin in the woods and who confront events so bizarre and horrific that they can only begin to fathom it as time quickly runs out.

"If we have done our jobs right, people will be trying to fill in the gaps for years," Whedon said. "Drew [Goddard] and I did fill in the gaps for years. We talked about this movie endlessly before we made it, even before we wrote it, because it’s the kind of world that we love to walk in.

"Also, the way I approach fiction is to not just tell a story but to create a world behind it so that everything has purpose. Every door, we know where it leads. We know what’s behind all of them, and that way, when people want to expand on it, they go, 'Oh, it’s there.'"

Whedon is the mastermind behind such hits as "Buffy The Vampire Slayer," "Angel," "Firefly," "Dollhouse" and "Dr. Horrible's Sing-Along Blog."

Goddard has also held producing and writing credits on "Lost," "Alias" and "Buffy The Vampire Slayer."

Since opening in theaters Friday to critical acclaim, the film has pulled in a respectable $14,850,000 over the weekend and has since earned a domestic total of $18,245,713, according to Box Office Mojo.

"The Cabin in the Woods" stars Chris Hemsworth ("Thor"), Fran Kranz ("Dollhouse"), Amy Acker ("Angel," "Dollhouse"), Richard Jenkins, Anna Hutchinson, Kristen Connolly (The Happening"), Brian J. White ("Stomp The Yard"), Jesse Williams ("Brooklyn's Finest").
