Luketic, a 31-year-old Melbourne film school graduate, has been sworn to secrecy about the movie, rumoured to have a budget of $130 million and a cast including Brad Pitt and Catherine Zeta-Jones.
Scripts with pages strategically missing had been printed on specially produced red paper that could not be photocopied, he said.
"I'm very limited in what I can talk about with Dallas," Luketic said.
But he did let slip some tidbits of gossip. Dallas will be set in Texas in modern times; it won't be a spoof of the TV series; it's not a comedy; and JR Ewing and his backstabbing, dysfunctional family will take centre stage.
"This is actually a very sprawling, epic movie," he said.
Dallas, which ran from 1978 to 1991, was considered opulent, but Luketic's film will take this to another level.
Luketic's first feature film, Reese Witherspoon's 2000 comedy Legally Blonde, made almost $200 million despite costing just $25 million.
