Double-booking can be a hilarious premise for comedy, as in the wedding rom-com films Bride Wars and You’re Cordially Invited in which two weddings are booked for the same venue on the same day, or a terrifying setup for horror, as in the 2022 film Barbarian in which a woman arrives at a rental home already occupied by a mysterious guest.

Do the opposing parties know each other or are they complete strangers? You might consider playing with narrative perspective and incorporating portions from opposing characters’ points of view or experimenting with a fragmentary structure to evoke suspense and disorientation. Is your story a comedy or horror of errors?
