Margaret Qualley, who plays Alex, is the real-life daughter of Andie MacDowell, who plays Paula. This show marks the first time both appear together in a production.
Alex frequently has dreams of a better life in Missoula, Montana, and in the second episode it is mentioned she wanted to live in Montana ever since reading "A River Runs Through It". Margaret Qualley, who portrays Alex, was born in Montana and spent her early years on a ranch in Missoula.
Andie MacDowell's real-life mom's name is Paula.
Two of the show's main actors originally hail from the Pacific Northwest area where it's set. Sean actor Nick Robinson is from Seattle, where the show takes place. Hank actor Billy Burke was born and raised in Bellingham, Washington, a city north of Seattle by the Canadian border (and very near the show's Victoria filming location).
In this series, Margaret Qualley (Alex) plays a character whose boyfriend subjects her to domestic abuse. In September 2021, very shortly before the show's release date, Qualley gave an interview to Harper's Bazaar in which journalist Molly Creeden asked her about the domestic violence lawsuit that singer-songwriter FKA Twigs (née Tahliah Debrett Barnett) brought against Qualley's ex-boyfriend Shia LaBeouf. Qualley replied, "It was important to me for [Barnett] to know that I believe her. It's as simple as that."
