It seems fitting to celebrate tax day, April 15th, with Ghostface hacking and slashing his way through more victims in Scream 4.

The first Scream was a clever little piece of film making that unfortunately ripped the heart out of horror films for years after its release. Instead of getting horror films we got tons of “me too” goofy horror films and wanna be hip riffs on horror. That’s a lot of baggage to pile on one movie but that just proves the impact that Scream had.

New images have been released for Scream 4, the upcoming sequel in the popular horror franchise from Wes Craven.

The images show returning stars Courteney Cox and David Arquette together, with another photo of Emma Roberts, who’s new to the series.

Also, the new full-length trailer was recently released, so you can watch that here below.

Scream 4 hits theaters on April 15, 2011.

At the recent Scream Awards, the first trailer for Scream 4 was finally shown. Since then, a couple of leaked versions of the trailer have shown up online, but all were of low quality, leaving everyone to wonder where the official trailer was.

Thankfully we did not have to wait too long, and the first official trailer for Scream 4 (we’re still not biting on the SCRE4M deal) is here to see! And surprisingly, it doesn’t look bad at all. The trailer immediately whisks you back to the Scream of old, and it looks like it will fit right in with the series, with the addition of some new technologies and “rules of surviving a horror movie,” naturally.

Two more impressive actresses have been added to the cast of Wes Craven‘s return to the Scream franchise. True Blood‘s own Sookie Stackhouse, Anna Paquin, and Veronica Mars and Forgetting Sarah Marshall star Kristen Bell have both signed on for roles in Scream 4 (er, SCRE4M, but we hope if we ignore that it’ll go away).

The two new additions join an already huge cast including returning stars Neve Campbell, Courteney Cox Arquette, and David Arquette, as well as newcomers Emma Roberts (Nancy Drew), Hayden Panettiere (Heroes), Marielle Jaffe (Percy Jackson & The Olympians: The Lightning Thief), Rory Culkin (Signs), Nico Tortorella (Make it or Break It), Erik Knudsen (Scott Pilgrim vs. The World), Anthony Anderson (The Departed), Adam Brody (The O.C.), Marley Shelton (Grindhouse), Alison Brie (Mad Men), and Mary McDonnell (Battlestar Galactica).

As many of you should know by now, Scream 4 has constantly been picking up steam over the past few months, and it’s not slowing down now.

After securing main returning stars like Neve Campbell, David Arquette, and Courteney Cox Arquette, as well as original screenwriter Kevin Williamson and director Wes Craven, it was time to find and acquire some fresh blood.

This began with the casting of Emma Roberts as one of the female heroines (and likely the lead female if this does turn into a second trilogy). Right around the time that Roberts was cast, Heroes star Hayden Panettiere and Rory Culkin were rumored to be up for parts as well…eventually progressing to confirmations.
