Singer Crystal Kay has been appointed to do a theme song for an American film. "HOLD ON," a rock-influenced number with entirely English lyrics, will be used in "Dolan's Cadillac," an adaptation of a Stephen King short story. The film is being directed by Jeff Beesley and stars Christian Slater and Wes Bentley.

Crystal Kay has sung several themes for Japanese movies and television series, but this will be her first for a foreign production. She was chosen for the tie-up by producer Ellen Wander, who listened to the previously unreleased song.

Crystal Kay is hoping this will help her achieve her goal of entering the U.S. market. Her most recent album, "Color Change!," includes two songs she created in Los Angeles with producers Jimmy Jam and Terry Lewis, known for working with popular artists such as Janet Jackson.

"Dolan's Cadillac" is scheduled to hit U.S. theaters in 2009. A Japanese release has not yet been decided.
