Early 2000s nostalgia is showing no signs of stopping, and now it’s reached the true crime boom. HBO Max’s latest star-studded miniseries is The Staircase, which depicts the 2003 trial of novelist Michael Peterson (Colin Firth) for the 2001 murder of his wife Kathleen (Toni Collette).
Following the first teaser, the new trailer for The Staircase sets up the conflicted couple, who had been married for nearly a decade at the time that Kathleen was found dead with extensive injuries that authorities asserted were inconsistent with an accident.
