What is it about?

The Staircase is a true-crime drama about a novelist believed to have killed his wife, and the subsequent trial that took place as a result.

Is it based on a true story?

Yes, it is. Petersen was accused of murdering his wife in December 2001; while Petersen maintained that his wife had fallen down the staircase, authorities argued that her injuries were consistent with blunt force trauma caused by bludgeoning.

The Staircase is actually specifically a dramatisation of an acclaimed French documentary of the same name (though it’s sometimes also called Death on a Staircase). The first instalment of the documentary was released in 2004, covering the crime itself and the initial reaction, while a follow-up was released in 2018, reflecting on the murder and its consequences with fourteen years’ hindsight.

You can watch the documentary version of The Staircase on Netflix.

Colin Firth plays the novelist Michael Peterson, who was accused of murdering his wife in 2001. Firth is known for a number of different films, including Pride and Prejudice, Love, Actually, and the Mamma Mia duology. He’s also recently appeared in Operation Mincemeat and Supernova (which is fantastic).

Toni Collette plays his wife Kathleen, who is murdered on a staircase (hence the title). Collette is a prolific actor, who you might recognise from murder-mystery Knives Out, Bowie-esque almost-biopic Velvet Goldmine, and the horror movie Hereditary. She also recently appeared in the TV series Wanderlust, which is well worth checking out.

Michael Stuhlbarg (Call Me By Your Name), Dane DeHaan (ZeroZeroZero), Sophie Turner (Game of Thrones), and Odessa Young (Shirley) also star.

Is there a trailer?

Yes, there is! You can see it right here.

Who writes and directs The Staircase?

The adaptation was spearheaded by director Antonio Campos, who’s been working on the series since 2008. Campos – who directs 6 of a total of 8 episodes of The Staircase – is best-known for films like Simon Killer and The Devil All The Time, and has directed episodes of The Punisher and The Sinner on television.

Why should I watch it?
