Scary Movie 4 is a 2006 American parody film directed by David Zucker, written by Jim Abrahams, Craig Mazin, and Pat Proft, and produced by Mazin and Robert K. Weiss. It is the sequel to Scary Movie 3 and the fourth installment in the Scary Movie film series, as well as the first film in the franchise to be released by The Weinstein Company following the purchase of Dimension Films from Miramax Films (who did still co-produce the film). The film stars Anna Faris, Regina Hall, Craig Bierko, Bill Pullman, Anthony Anderson, Carmen Electra, Chris Elliott, Kevin Hart, Cloris Leachman, Michael Madsen, Dr. Phil McGraw, Leslie Nielsen, Shaquille O'Neal and Molly Shannon.

The film marks the final franchise appearances of the main stars, Faris and Hall (who portray Cindy and Brenda, respectively), and concludes the original story arc. This was initially intended to be the final film in the Scary Movie film series, until Scary Movie 5 was released in 2013. The film grossed $178 million on a $40 million budget, becoming the third highest-grossing film in the series.
