What’s new to watch this week

The Staircase (May 5, Neon)

Crime novelist Michael Peterson is accused of bludgeoning his wife Kathleen to death after she is found dead at the bottom of a staircase in their home in this eight-part drama based on a true story that included a 16-year court battle. The impressive cast includes Toni Collette, Colin Firth, Sophie Turner, Patrick Schwarzenegger, Dane DeHaan, Olivia DeJonge and Michael Stuhlbarg. ‘‘The linchpin of this delicate portrayal is Colin Firth’s performance as Michael. Best known for playing romantic leads and other charismatic types, he disappears, here, into a far murkier character,’’ wrote Time magazine’s Judy Berman.

Star Trek: Strange New Worlds (May 5, TVNZ OnDemand)

Both a spin-off of Star Trek: Discovery and a prequel to the original 1960s series, this 10-episode sci-fi drama follows the crew of the USS Enterprise under the stewardship of Captain Christopher Pike (Anson Mount). Ethan Peck and Rebecca Romijn also feature, while specific links are promised to one of the most beloved movies from the long-running franchise.

Finding Alice (8.30pm, May 5, Eden)

Keeley Hawes and Joanna Lumley star in this sixpart British dramedy about a woman whose excitement of finally being able to move into her dream home is shattered by a freak accident that results in her beloved husband’s death. Not only does she have to navigate his absence, but also a storm of secrets and debt he has left behind. ‘‘Strikes the right balance between drama and comedy, sadness and laughter,’’ wrote Decider’s Joel Keller.
