Words in her mouth.

Posters for the film "Silent Hill" have become a fan favorite. The only glitch is, some of the more active and creative fans are law-breakers.

The poster shows a mysterious young girl without a mouth. The image has proved so provocative that graffiti enthusiasts can't resist filling in the missing feature.

According to Hollywood-based design shop and advertising agency Shoolery, which produced the campaign, the "Silent" bills have "become one of the most defiled movie posters to come along in a while." In New York City subways, the modified posters now show the girl with fangs, buck teeth, screaming lips, mustaches, pacifiers, and cigarettes instead of a non-mouth.

In a reversal of usual roles, Mark Shoolery, chief executive of the namesake agency, loves the spray-paint crowd. "As artists ourselves, we always get a kick out of other artists who feel they have imagery to contribute that can embellish our concept. We are pleasantly surprised by this grass-roots audience response to our work, and are honored by the attention it has been generating," he said.

How about generating some ticket sales? As of May 1, "Silent Hill" ranked fourth place at the weekend box office, with cumulative ticket sales of $34.2 million. The movie, produced by Sony Pictures Entertainment and TriStar, opened in theaters on April 21 and led the weekend at the box office, claiming $20 million despite horrible reviews.

To a degree, the subway graffiti tie-in works with the product. "Silent Hill" is a dark horror film about another dimension inhabited by semi-humanoid creatures. Yes, the cast includes a girl, but the actress (Jodelle Ferland) has all her facial features intact.

Law-abiding "Silent" fans that like the poster can download an electronic wallpaper version of it for $1.99 from the movie's Web site at www.sonypictures.com.
