An insider is also said to have confirmed that Ridley Scott is in Australia for Prometheus 2.
"It's the best kept secret at the moment, that Ridley is here to film the Prometheus sequel," the insider stated. "The news couldn't come at a better time, with Gods Of Egypt and San Andreas wrapping soon people were looking for the next project."
