Mushroom Murders: Melanie Lynskey to star as Erin Patterson in new limited series

Emmy-nominated actor is also executive producer of the Paramount+ series, which will dramatise the Australian true crime case

The Emmy-nominated New Zealand actor Melanie Lynskey has been cast as triple murderer Erin Patterson in a new limited series titled Mushroom Murders: There’s More to Unearth, which will premiere on Paramount+ in 2027.

The series follows the 97 days between the notorious 2023 lunch – at which Patterson allegedly served toxic death cap mushrooms to her estranged in-laws, hidden in individual serves of beef wellington – and her arrest.

Served at her home in Leongatha, Victoria, the meal killed her husband’s parents, Don and Gail Patterson, and his aunt Heather Wilkinson, leading to Patterson’s eventual conviction.
