Colin Firth is set to play the lead role in The Staircase

There's not yet a specific date for the release, but a spring release indicates that the eight episodes could drop around April time. We'll keep you posted!  

Toni opened up to Lorraine Kelly in 2021 before filming began for the show, explaining she'd never met the Pride & Prejudice actor. "It's an amazing cast and fascinating story and, in fact, it kind of encompasses the making of the documentary in the dramatised version," she said at the time.

"I don't know Colin, I met him years ago at a dinner, but everyone says he's just so normal and so lovely. I think it'll be fun, I'm excited!"

And it's not just Colin and Toni leading the cast, Game of Thrones actor Sophie Turner is also set to appear, playing the role of Margaret Ratliff, one of Michael's adopted daughters.

The series will be directed by Antonio Campos, who served as a producer on American Crime Story: The Assassination of Gianni Versace and directed Tom Holland's 2020 Netflix hit The Devil All the Time.
