Marlon Wayans, who originally created the "Scary Movie" franchise alongside his brothers Keenen Ivory and Shawn back in 2000, said in an interview that the studio asked the Wayans Brothers to return for "Scary Movie 5", but the brothers declined. Marlon Wayans later released his own horror movie spoof "A Haunted House" (2013) which performed so well at the box office that it spawned its own franchise, with "A Haunted House 2" to be released in 2014.
"The Evil Dead" remake is spoofed although it was released only one week before "Scary Movie 5". The "Scary" producers approached the "Evil Dead" script and basically spoofed the trailer. The "Fifty Shades of Grey" movie isn't even in production yet, but is already spoofed in this film.
David Zucker directed the additional/re-shoots from January to February 2013. Main actress Ashley Tisdale told in several interviews that the material from the re-shoots (and ADR sessions) make about 60% of the final theatrical cut. Director Malcolm D. Lee didn't have anything to do with the editings since he was already engaged in doing "The Best Man Holiday" (2013) by the time they did them. Lee didn't even show up at the "Scary Movie 5" premiere in LA for unknown reasons.
Since Here Comes Honey Boo Boo (2012) isn't very known in Germany, the reference to the show was replaced by I'm a Celebrity, Get Me Out of Here! (2003) in the German dubbed version, which is a hit reality series on German TV - similar changes were also made in other countries, such as Brazil. The dubbing actor who voices Dom Kolb in the German version is actually the same who usually dubs Leonardo DiCaprio.
David Zucker said in an interview that the movie's release actually had a 3 year wait because the studio tried to convince him to return to direct. Finally, the studio and Zucker agreed that Zucker returns, but as a writer. Then the studio hired Malcolm D. Lee to direct after Lee helmed "Soul Men" (2008) for the same studio. Before Zucker was added to write. The initial script was delivered by writers Stephen Leff, John Aboud and Michael Colton. Zucker rewrote it first together with Lee and later again with his long-time writing partner Pat Proft.
The spell 'Gort Klaatu Barada Nikto' was originally heard in the 1951 science fiction movie "The Day the Earth Stood Still" as a phrase with which to awaken Gort, the mechanical guardian, and ordering him to protect Klaatu, the alien visitor played by Michael Renny. The phrase was also used in the movie's 2008 remake starring Keanu Reeves and Jennifer Connelly and a similar phrase.is used in Army of Darkness.
In the scene where Charlie Sheen and Lindsay Lohan are in bed and the cat jumps on the bed, Charlie says "Get out of here, Emilio!" This is likely to be a reference to Charlie's brother, Emilio Estevez.
Filming begun on Tuesday, September 4, 2012 and wrapped on Thursday, October 25, 2012. Additional footage recordings and re-shoots occurred between January and February, 2013 with ADR sessions taking part in March and April.
Both David Zucker and the sound mixer, Chris Durfy are avid Green Bay Packers fans and Wisconsin natives. They both have a cameo in the Black Swan spoof near the end of the movie dressed as Packer fans for the Lambeau Leap.
The saying Klaatu Barada Nikto was also used in The Evil Dead by Ash to summon up the demon from the Necronomicon Ex Mortis, The Book Of The Dead. (Ash also screws up reciting the phrase thus causing all sorts of problems in Evil Dead III too). Incidentally Nikto was also the name of a chatacter that appeared in Jabba The Hutt's palace in Star Wars Episode VI:Return Of The Jedi.
