Fans who submitted their name on the official website during the film's theatrical run were treated with having their name listed in the film's ending credits on the DVD/Blu-ray release of the film as thanks from Paramount for making the film such a success.
The theatrical release of the film had no closing credits. After the final scene, a title card offered the 'fate' of Katie and Micah, then there was a brief showing of copyright and other protections, and the screen went black for a few seconds before the standard 'blue screen' showing the movie's rating appeared.
The acting/producing/directing credits appear for one frame after almost a minute of darkness after the copyright credits on some DVD editions.
Epilogue text reads: "Micah's body was discovered by police on October 11, 2006. Katie's whereabouts remain unknown."
