Who She Is
The final girl who stands up to Art the Clown came to acting late, and on a dare to herself. LaVera grew up in Philadelphia and was drawn to acting as a kid, and she trained while at Temple University, but it wasn’t the plan. She studied toward a law degree, switched to English with a minor in Italian, then left school for what she calls “a really great white collar job” as an optician in the city.
Her grandmother changed that. She had always wanted to be a dancer and an actress and never got the chance to try. “When she was on her deathbed, I remember being with her and thinking, ‘she didn’t even get to attempt her dream,'” LaVera has said. Shortly after her grandmother died, LaVera quit her job and took her first acting class that same night. The class happened to be at a casting office, which started calling her in for auditions before she had an agent.
The Work
Her first time on a real set was as a body double on fellow Philadelphian M. Night Shyamalan’s Split (2016). She doubled all three young leads, Anya Taylor-Joy, Haley Lu Richardson and Jessica Sula, for close-ups. That includes the knife on Marcia’s stomach, which she has confirmed is her. Shyamalan noticed her on set, and the experience made her want to act full-time. Short films and small TV parts followed.
The Movies, and What She Did on Them
Terrifier 2 (2022): when the casting breakdown for Sienna arrived, LaVera didn’t think she was right for it and forwarded it to an actor friend. She auditioned anyway, without having seen the first Terrifier. After her first callback she deliberately kept not watching it so it wouldn’t change her choices. She watched it the day she found out she’d booked the part.
Damien Leone had been impressed by her martial-arts reels. She also happened to look like the teenage angel-warrior he had sketched for an early poster. After a reading with two future castmates he cast her in the room. “There was never a runner-up,” he said. To prepare, she has said, she asked Leone which final girls inspired Sienna. He named the heroines of Halloween, Scream, The Terminator and Alien. She rewatched them all, listed their traits and sent him a pamphlet of the ones Sienna could share. Leone also made her a playlist heavy on Fleetwood Mac and Chromatics. Critics singled her out. One review said she “rules as Sienna in her angel-winged fantasy armor,” and another credited her with “pure star power.”
Terrifier 3 (2024): she returned as Sienna in Leone’s Christmas-set sequel. Critics praised how she played her character’s trauma and survivor’s guilt. The film opened at number one at the U.S. box office with about $18.9 million.
Between the sequels she played Alessa in Joe Lam’s The Fetus, opposite Bill Moseley as her father. She also starred in Federico Zampaglione’s The Well (2023) and presented it at FrightFest. In Darren Lynn Bousman’s Twisted (2026) she plays Paloma, a con artist who slips between personas.
Signatures, Habits and Behind the Scenes
- She teaches kickboxing. “I’d go insane if I didn’t have something to hit,” she said.
- She has said she doesn’t recommend copying her leap: quitting a steady job on the same night she started classes was, in her words, “a really irresponsible one,” and she is proud of it anyway.
Why She Matters
Terrifier began as a showcase for Art the Clown. LaVera gave the sequels a hero worth rooting for: physical, wounded and stubborn, a final girl who fights back on camera because the actress can actually fight. She has grounded a franchise built on excess, and she represents a new kind of horror star, one who built her career through reels, small parts and the indie circuit rather than a studio launch.
