The new science-fiction horror film - Alien and the third film adapted from the Marvel comics - Thor: Ragnarok, will be shot in Australia, with the Turnbull government offering Universal Studios Hollywood $AU47 million ($NZ49 million) in agreeing to attract the blockbusters, which are anticipated to make about 3000 local jobs.

The latest Alien film by English film director and producer - Ridley Scott, which is yet to be given a title, will be the sixth installment in the film series after 2012's science fiction film - Prometheus, which was a prequel to Ridley Scott's 1979 original. Director Ridley Scott's latest Alien movie is being made by 20th Century Fox studios.

While Thor: Ragnarok, will star Australian actor, famous for his roles as Kim Hyde in the Australian TV series Home and Away, Chris Hemsworth, will be the third installment in the series. And Thor: Ragnarok is being made by the American film studio Walt Disney.
