Nicole Kidman is reteaming with her Portrait Of A Lady director, Jane Campion, for the second season of thriller Top Of The Lake. Kidman’s participation has been the subject of on-and-off rumors, with the BBC confirming the casting today as the actress arrived in Sydney to begin filming with series star Elisabeth Moss. Titled Top Of The Lake: China Girl, the story will see Moss’ Detective Robin Griffin investigating the case of an unidentified body which washes up on Sydney’s Bondi Beach. As previously reported, the second installment also features Game Of Thrones star Gwendoline Christie in a “major role.”

Created by Campion and Gerald Lee, the mini first aired in 2013 with Moss’s Griffin investigating the disappearance of a pregnant 12-year-old girl. She won a Golden Globe for the role in 2014. The Season 2 narrative is said to pick up four years after the first ended.

Brian Walsh, chief of Oz’s Foxtel, told The Daily Telegraph it had taken a year to ­secure Kidman who signed on last week before jetting straight to Sydney for rehearsals. “I am very excited to be coming home to work with darling friend Jane Campion, whose work I ­respect and admire,” Kidman told the paper. “I’m also so happy to be joining the ­incredible Elisabeth Moss.”

S2 cast members also include Liv Hewson, David Dencik (Tinker Tailor Soldier Spy), Alice Englert (Beautiful Creatures) and Ewen Leslie (The Daughter). The series will air on BBC Two in the UK and on SundanceTV and Hulu in the U.S.

Campion is co-directing with Ariel Kleiman (Partisan). Campion and Lee also return as co-writers. Top Of The Lake Season 2 is produced by See-Saw Films for BBC Two in co-production with SundanceTV; BBC First and Foxtel in Australia; and in association with Hulu; France’s ARTE and BBC Worldwide. Exec producers are Campion with See-Saw’s Emile Sherman, Iain Canning and Jamie Laurenson, alongside Lucy Richer for the BBC.
