At this time of year, there are several films, we simply have to watch - from Elf to Love Actually and Home Alone.
But one festive flick we simply can't go without seeing is the Nancy Meyers movie, The Holiday.
Starring Cameron Diaz, Kate Winslet, Jude Law and Jack Black, the film follows two women, Amanda and Iris, as they swap homes over the holiday season.
Iris travels from the UK over to Los Angeles to stay in Amanda's swanky house, while Amanda leaves LA behind for a cosy countryside cottage in Surrey.
Along the way, both manage to find love and learn a lot about themselves - it's super heartwarming.
However one fan of the film has just shared an incredibly chilling take on the Christmas rom-com.
A Reddit user named tectonic_fever shared a post on the Fan Theories forum, suggesting Kate Winslet's character had much darker motives for using the Home Exchange website.
They revealed how they liked to think that Iris (Winslet) and her brother, Graham (Law), were really deceiving Amanda (Diaz) the entire time and were actually planning to murder her and steal her wealth.
"This idea makes the mediocre Christmas movie so much more entertaining," they proclaimed.
They went on to explain: "Kate Winslet and Jude Law are laying a trap where he will seduce Cameron Diaz, marry her, kill her, and inherit her fortune.
"Jude Law already murdered his first wife so he could inherit her house.
"Now he and his sister have used the house swap scheme to get Cameron Diaz into their town, while Kate Winslet can investigate and make sure Cameron has enough money and property (and no family/entanglements) to be worth the effort of seducing her and then disposing of her.
"Kate is so overjoyed to see how grand and luxurious Cameron's house is because she knows she and Jude have hit the jackpot."
"Meanwhile, Jude carefully sets up an 'accidental' meeting and manipulates Cameron to develop a relationship and get his claws into her," they continue.
"Everything that follows is orchestrated to carry out their plot."
The person adds: "Kate Winslet was maybe also planning to seduce and marry the old screenwriter and wait for him to die and leave her his house/fortune, until Jack Black interferred."
Fellow Reddit users were amused by the theory and wanted to hear more about it.
One person commented: "More detail and evidence to support this would be great. I like it."
Another said it reminded them of a Crimson Peak storyline.
