Tama Poata's wide-ranging contributions to our culture can be glimpsed through his appearances on-screen: from campaigns for Māori land rights (in 1975 doco Te Matakite O Aotearoa) and against the Springbok tour (Patu!), to his many acting roles. He also directed documentaries and wrote landmark 1987 movie Ngati, the first feature written (and directed) by Māori.
The films of Jim Marbrook include feature-length documentaries on speed chess maestros (2003 award-winner Dark Horse), psychiatric hospitals (Mental Notes) and environmental issues in New Caledonia (Cap Bocage). Marbrook also lectures in screen and television at Auckland University of Technology.
