Doralynn Mui
Doralynn Mui is an Asian Canadian actress from Vancouver, Canada. She is best known for her roles as Joan Berkeley in Riverdale (CW) and Fiona Jennings in One Of Us Is Lying (Peacock). Other credits include Deadly Class (SyFy), So Help Me Todd (CBS) and Two Sentence Horror Stories (CW).

Doralynn was born in Vancouver, Canada, the second youngest of four children. When she was younger, although she loved to act in plays and re-enact soap operas for her friends, Doralynn never considered "acting" as a real career path. After dipping her toe in student films and indie projects while in school, she took the leap into professional acting.

Doralynn is active in the indie film community. She has held leading and supporting roles in indie films such as Bunny Man, Mattress, All-in Madonna and Four Walls. In addition to acting, she studied Film Production and Communication at Simon Fraser University.

In 2019, Doralynn joined the cast of Deadly Class as the vengeance-seeking Riku. In 2021, Doralynn garnered positive accolades for her starring role as the conflicted goth in Two Sentence Horror Stories: Bag Man, a horrific spin on John Hughes' The Breakfast Club. Doralynn also received many positive reviews for her performance as Fiona Jennings in Season 2 of One Of Us Is Lying, being named as a "top talent for the season."
