Online piracy has become a significant concern for the film industry, with websites like Filmyzilla, Tamilrockers, and Movierulz offering unauthorized downloads of movies. These websites often provide movies in various languages, including Hindi, Telugu, Tamil, and Malayalam. The ease of access and availability of pirated content have made it challenging for the film industry to combat piracy.

The movie "Knock Knock" revolves around a man named Ben (played by Keegan-Michael Key) who is home alone when two strangers, Eve (played by Kathryn Hahn) and Lucas (played by Nick Swardson), knock on his door.
