Shot in six days.
Tyler Perry says the idea was conceived after watching the film Top Five (2014). In that film, Chris Rock's character enters a movie theater and sees movie goers lined up for a fictional Tyler Perry movie about Madea fighting ghosts in a haunted house. That movie was also called "Boo!"
The film netted $74 million between domestic and international runs and $72 million of that was domestic. Having only a six-day shooting schedule, it made roughly $12.3 million per day of shooting.
In the scene where BJ walks through the living room, the actor is holding the iPad of the film's script supervisor which happened to have a PDF of the script on the screen as the prop was improvised as cameras started rolling on the scene.
While both Bam and Hattie call Madea by her given name, Bam also calls her 'Dea', and Hattie calls her 'Ma'.
