When deciding on promotional tie-ins, "The Messengers" chose well, keeping its demographic in mind at all times. What young adult wouldn't want to win a trip away from home? Enter the Eternal Escapes Sweepstakes to win $2,000 in travel from Student Universe. "Are you trapped at home and desperate to get out?" the site asks. Well, of course.

Enter to win a trip away from mom and dad

The See Beyond Sweepstakes is set up in a forum on IMEEM.com, an online community for sharing media. The grand prize -- a private screening of "The Messengers" for the winner and 50 guests, 51 Teddy Scare Plush Bears and a $500 gift certificate to PaniksToyBox.com -- is promoted in a way that targets the primary consumer: "Now it’s your turn to see something that others cannot: a private screening of 'The Messengers.'"

The Proof of the Paranormal Sweepstakes -- a chance to win a haunted portrait -- explores yet another variation on the theme. Haunted Portraits and Shakefire.com --  a movie, music, game and book-review website -- teamed up on this one.

Created by artist Norm Lanier, Haunted Portraits are eerie pictures that change, without the help of electronics or mechanics, when you walk by them. Each portrait is signed and numbered in a limited edition of only 100. Examples of this unique art form can be found on Norm's website.
