The so-called home invasion subgenre of horror has been done numerous times before. The first house invasion film can be dated back to 1909 with D.W. Griffith’s The Lonely Villa, a movie about a man barricading him and his family in their house from burglars. The genre can range from more psychological thrillers like Panic Room (2003), whereas films such as Funny Games (1997) and The Strangers (2008) are more on the slasher genre, with grotesque blood and gore.
