Director Richard Kelly wrote on his MySpace page that his upcoming sci-fi movie The Box is completely finished and ready for its Oct. 30 release date.

"The release date has been shuffling around a bit, but this is common with studios, and everyone feels like this is the best date for the film," Kelly posted last week. Based on the 1970 short story "Button, Button" by Richard Matheson, the film is written and directed by Kelly and stars Cameron Diaz and James Marsden as a couple who receive a box with a mysterious power.

In other updates, Kelly wrote:

♦"The film is completely finished. Principal photography was completed in March 2008, and it was officially delivered to WB right before Christmas 2008. A March 2009 release was briefly considered, but a fall 2009 release was always a better fit."
♦"We shot in Massachusetts and Virginia. The film takes place predominantly in Virginia, 1976."
♦"The running time is 1 hour 55 minutes long, including end credits. ..."
♦"There is more than 300 visual effects shots, which required eight months of post-production. ..."
♦"Win Butler, Regine Chassagne (of Arcade Fire) and Owen Pallett (Final Fantasy, frequent collaborator with Arcade Fire) recorded more than 80 minutes of score for the film."
♦"Here is a list of artists whose songs appear in the film: Grateful Dead, Derek & The Dominos, Wilson Pickett, The Marshall Tucker Band, Scott Walker."

The official Web site will go live this summer.

Kelly added: "This is my most personal film to date, and I'm very proud of how it turned out."
