Siren: The Voices of Shelley Beattie

Wednesday 23 September, only on HBO Max

Same day as US (1 episode)

While searching the internet one day, Hollywood veteran Marlee Matlin came upon the story of athlete Shelley Beattie – a fellow deaf woman whose life felt eerily like her own.

Siren: The Voices of Shelley Beattie, directed by acclaimed documentary filmmaker Irene Taylor, explores the parallels between the two legendary women in a haunting portrait of strength, beauty and resiliency.

A Killer Story

Friday 11 September, only on HBO Max

Episodes drop weekly, same day as US (3 episodes)

A Killer Story examines a polarising murder case that spanned more than two decades and captured national attention. At the centre of the case is Dana Chandler, accused of killing her ex-husband and his girlfriend in 2002. Lacking forensic evidence, the murder case is litigated over three arduous trials with the series unspooling a complex tale of family conflicts, betrayal, prosecutorial misconduct, competing narratives and confirmation bias. More than a murder mystery, A Killer Story probes true crime obsession and the dangers of blinkered certainty in a case where the truth may never be known.

Episodes drop daily, same day as US (4 episodes)

Never-before-seen footage from the making of Juiced - the ill-fated hidden-camera prank show featuring O.J. Simpson. An extreme experiment in the reality TV genre during a time that fused shock value and celebrity culture at any cost, for Simpson, the show was a misguided and desperate attempt to rehabilitate his public image. But just as producers were about to launch this ill-fated attempt to blend reality television with the crime of century, a mystery saboteur brought the whole thing crashing down from within.

Backrooms (September 25)

The hit movie Backrooms from director Kane Parsons and starring Chiwetel Eijofor and Reinate Reinsve will have its streaming premiere on Friday September 25.

The films follows a furniture store owner and would-be architect (Ejiofor) who gets lost in a world somehow connected to his store, filled with an endless network of interconnected rooms where time bends and the only thing scarier than getting lost is the sense that something is lying in wait. 

But when he doesn't show up for an appointment, his therapist wades in to rescue him (Reinsve).
