THE STAIRCASE (2022)

Kathleen Peterson’s fatal fall down her North Carolina staircase in 2001—and the subsequent court cases that ended with her husband, novelist Michael Peterson, being convicted of murder—has spawned podcasts, a groundbreaking 2004 documentary and an intriguing series starring Toni Collette and Colin Firth. While it’s not a traditional whodunit, Firth, who plays Michael, has described it as “the study of a family and the whole idea of mystery even with people you’re closest to—it compels you.” Peterson still maintains his innocence.
