In this episode of Stuff You Should Know, Josh Clark and Chuck Bryant explore the horror trope of threatening phone calls coming from inside the house. The hosts trace this concept back to its origins in a real 1950 murder case, where a 13-year-old babysitter was killed in Missouri, and explain how this tragedy influenced the development of a widespread urban legend.
The hosts examine how this premise became a foundation for several notable horror films of the 1970s, including "When a Stranger Calls" and "Black Christmas." They also discuss how modern technology, particularly cell phones, has affected the impact of this once-powerful horror device, forcing storytellers to develop new methods of creating tension in their narratives.

A chilling horror trope from the 1960s features a young babysitter receiving menacing phone calls while watching children. The story typically culminates in a terrifying revelation: the threatening calls are coming from inside the house, suggesting an intruder's presence and potential harm to the children upstairs.
This urban legend draws inspiration from a tragic real-life incident: the 1950 murder of 13-year-old Janet Chrisman in Missouri. While babysitting for the Romack family, Janet was brutally murdered, with the home's phone torn from the wall—a detail that would later influence the "call from inside the house" narrative. The porch light left on suggested Janet may have recognized her attacker.
The "call is coming from inside the house" trope has been immortalized in several iconic horror films, including "When a Stranger Calls" (1979), "Black Christmas" (1974), and "Halloween" (1978). The device's effectiveness stems from its ability to shatter the victim's sense of safety, revealing that danger has already infiltrated what should be a secure space.
Josh Clark and Chuck Bryant discuss how modern technology has diminished the impact of this once-powerful horror device. Bryant notes that cell phones have "screwed up" the concept, as receiving calls from within one's house is now commonplace. The ubiquity of mobile phones has forced filmmakers to seek new creative techniques to maintain tension and exploit audience fears, moving beyond this classic but increasingly dated plot device.

Origins of 'Call From Inside the House' Urban Legend
The horror genre has spawned numerous tropes that have become legendary in their ability to evoke terror, but few have struck a chord as chillingly as "the call is coming from inside the house," a narrative device used to great effect in several iconic films.
The trope "the call is coming from inside the house" is notably used in the genre-defining films such as "When a Stranger Calls" (1979), "Black Christmas" (1974), and "Halloween" (1978), and has been an enduring narrative device in horror. The power of the trope lies in its sudden reversal of the victim’s sense of safety, amplifying the fear by demonstrating that the perceived danger isn’t just near—it’s already breached the sanctity of the home. Josh Clark specifically mentions "When a Stranger Calls" as an example where this trope plays a pivotal role. The horror unfolds as the protagonist realizes that the threatening calls they've been receiving are coming from within their own abode, a place presumed to be a refuge from outside threats.
The terrifying notion is believed to be inspired by the real-life tragedy of Janet Chrisman's murder. The idea that the source of fear is much closer than it seems taps into deep-seated anxieties about vulnerability and the invasion of personal spaces. The trope employs this narrative element to create a sense of inescapable danger, leaving audiences with enduring unease.
Legendary Figures in Horror
The ubiquitous presence of cell phones has changed the landscape for horror storytelling, prompting creative adaptation to preserve the suspense and tension that classic tropes once effortlessly provided.
Josh Clark and Chuck Bryant hold a discussion on how the classic horror trope "The call is coming from inside the house" has lost its edge in the age of ubiquitous cell phone use.
They explain that historically, this legend preyed on the assumption that calling your own number from inside your home was impossible, which heightened the terror when a victim realized the call was coming from within the house. The revelation that an intruder was not only inside but also using one's own landline to deliver threats created a sense of helplessness and isolation. Nowadays, the commonality of cell phones means that receiving calls from inside the house happens all the time and is not unusual or unnerving, thus diminishing the trope’s effectiveness. The reality that a call's origin can be hard to trace with cell phones further erodes the scenario’s ability to provoke fear. Bryant states that cell phones have indeed "screwed up" this classic horror concept.
