The Hive (2014),
The Curse of Sleeping Beauty (2016),
Polaroid (2019),
Sightless (2020),
Jane (2022), and
The Strangers film series have garnered her the reputation as a
scream queen. In April 2018, Petsch collaborated with sunglasses company Privé Revaux and released her own collection of sunglasses. Petsch has a
YouTube channel, stating that the inspiration to start one was so fans could know the "real her" outside of acting. ==Personal life==
