New South Wales premier Nathan Rees announced that filming would take place at Fox Studios in Sydney, with pre-production to start in July and principal photography to commence in November.
"The production is expected to employ 500 people at any given time, including 100 performers, 200 crew and thousands of extras," Rees said.
"Securing this movie will ensure skilled film crews stay in NSW. Films such as this invest heavily in the local economy and (have) flow-on effects for local services such as transport, construction and the hotel industry."
Green Lantern is set for release on December 17, 2010.
