Scott and Cruise were working on the much-anticipated follow-up to the 1986 film as late as Friday, according to The Hollywood Reporter.
The two apparently made a research visit to a Naval air station in Nevada last week.
Talk of the sequel began back in November 2010. Producer Jerry Bruckheimer told us at the time, "We've been talking about it since the movie came out and it was a big hit. Tom Cruise took a run at it many years ago and we just couldn't crack it. So we'll see what happens now."
A Paramount executive confirmed in May that plans had been solidified with Cruise, Scott and Bruckheimer returning and Peter Craig writing the script.
