Anna Faris and Regina Hall are back as the loveable, dim-witted Cindy Campbell and her self-serving, sex-crazed pal, Brenda, respectively - joined this time around by Craig Bierko ("Cinderella Man"), as the cute-but-utterly clueless Tom Ryan. Together, they battle to save the world from a ruthless alien invasion. And, in true Scary Movie tradition, the outrageous celebrity cameos are non-stop. Those featured include: Carmen Electra, Shaquille O‚Neal, Dr. Phil, Bill Pullman, Chris Elliott, Molly Shannon, Michael Madsen, rappers Chingy and Lil' John, Leslie Nielsen returning as our fearless Commander in Chief, plus many, many more surprises.
