Writer/director Parker Finn’s feature debut “Smile” boasts the thinnest of premises based on a laundry list of horror movie trends and tropes, from the historical to the contemporary. Based on his 2020 short film “Laura Hasn’t Slept,” Finn inserts the latest hot topic in horror — trauma — into a story structured around a death curse chain, as seen in films like “The Ring,” “It Follows” and “She Dies Tomorrow.” All that’s needed to pass along the curse is a mere smile, but it’s the kind of chin-lowered, eyes-raised toothy grin that communicates something far more devious than friendly.
That’s pretty much the movie right there, but Finn fleshes it out with some dizzying cinematography by Charlie Sarroff, a creepily effective score by Cristobal Tapia de Veer, and a believably twitchy lead performance from Sosie Bacon. Oh, and jump scares, a whole lotta jump scares.
Back in 1942, horror producer Val Lewton pioneered a technique in the film “Cat People” that’s now referred to as the “Lewton Bus.” If you’ve ever seen a horror movie, you know it: a moment of slowly building tension that culminates in some shrieking noise from a source that is revealed to be harmless, but sends the popcorn flying nevertheless: a ringing phone, a home alarm system, the brakes on a bus. It’s a technique that Finn liberally abuses in “Smile,” almost to comedic effect.
