When “Scream 4” hits theaters on April 15, the ghost-face killer Roger Jackson will be back for more.

The main characters will remain the same: Neve Campbell as Sidney Prescott, David Arquette as Sheriff Dewey Riley, and Courteney Cox as Gale Weathers, a news reporter.

Emma Roberts, Hayden Panettiere and Kristen Bell are the new “screamers,” literally screaming throughout the movie as they witness more of ghost-face’s bloody stabbings.

With all the new characters in “Scream 4,” it’s no longer just a sequel, but the start of a new trilogy.

Wes Craven, whose previous movies are shockingly suspenseful, will direct the movie. Kevin Williamson, the screenwriter, wrote both “Scream” and “Scream 2,” along with the original draft of “Scream 3.”

Both Craven and Williamson are signed for two more films following “Scream 4,” depending on its success. Maybe the new trilogy will be called “Shriek” but who knows, why change the name after four movies? It doesn’t get old.

Even though the title will remain the same for the fourth movie, the rules have definitely changed. Modern audiences have become savvy to the rules of the originals, and ghost-face has never been predictable.

The new main rule is to expect the unexpected. Everyone is a possible target, and the ghost-face is expected to videotape his murders as a new sick twist to his stabbings.

But even though most rules have changed for this new generation of terror, one remains from the first film. Don’t even think about screaming.
