Vajna me Mario Kassar ki a Nick Stahl me Claire Danes kia hoki mai hei John Connor me Kate Brewster i tetahi atu kiriata. I awhina te Kaiwhakahaere a Jonathan Mostow ki te whakawhanake i te tuhinga, na John Brancato raua ko Michael Ferris i tuhi, ana ka tiimata te mahi i te 2005 i muri i te otinga o tetahi atu kiriata. I mohiotia i taua wa ko te mahi a Arnold Schwarzenegger ka iti, i te mea kua riro ia hei Kawana o California. I rapu nga kaihanga kia utua e Warner Bros. te pikitia pera i a raatau mo Terminator 3. I te tau 2005, i kii a Stahl ka hurihia a John raua ko Kate i te wa e eke ana te korero ki mua. I te tau 2006, Metro-Goldwyn-Mayer (he kaiwhaiwhai ki Orion Pictures me nga rangatira o tenei wa o te whare pukapuka Hemdale Film Corporation, te kaiwhakarato me te kaiwhakanao o te kiriata taketake, i whakaritea) kia tohaina te kiriata tuawha hei waahanga o te kaupapa a te Tumuaki hou a Harry Sloan ki te hanga i te taiwhanga hei kaitakaro Hollywood.I te Mei 9, 2007, i panuitia ko nga mana whakaputa mo te raupapa Terminator kua heke mai i te Vajna me Kassar ki te Kamupene Halcyon. I tūmanako nga kaiwhakanao ki te tīmata i tētahi toru hou. I utua te hoko ki te nama na Pacificor, he tahua tahua mai i Santa Monica. I te Hōngongoi 19, ko te kaupapa i roto i te ture ture na te whakawakanga i waenga i te MGM me te kamupene a Halcyon T Asset. He wā motuhake a MGM mō te 30 rā ki te whakawhiti kōrero mō te tohatoha o ngā kiriata Terminator. I te wa e whakawhitiwhiti ana mo Terminator 4, i paopao a Halcyon i ta raatau tono tuatahi, ana ka whakamutua e MGM nga whakawhitiwhitinga korero. I muri i te mutunga o nga ra 30, i kii a MGM kaore i te tatau te waa i whakamutua ai nga whakawhitiwhitinga me te wa e tuwhera tonu ana to raatau wa motuhake. I tono a Halcyon ki te kooti kia whakaaetia kia whakatata atu ki ētahi atu kaiwhakarato. I muri mai, i whakatauhia te whakawa, a, i whiwhi a MGM i te mana 30-ra mo te whakakahore tuatahi ki te putea me te tohatoha i te kiriata Terminator tuarima. I te mutunga, i utua e Warner Bros. $ 60 miriona ki te whiwhi i nga mana tohatoha o te United States o Terminator Salvation; Sony...  Pātai: Nā wai i whakatārewatia ngā whakawhitiwhitinga?
Ko te MGM
