James Cameron has taken time out from crafting the upcoming four Avatar sequels to return to one of his old films, one he says is as up-to-the-minute as ever - Terminator 2: Judgment Day.
Cameron converted the 26-year-old film - in which one robot with artificial intelligence battles another to stop nuclear annihilation - into a 3D format that hits movie theatres August 25.
It arrives just as escalating tensions over North Korea's nuclear ambitions are in the headlines.
"I think the film is as timely as it ever was, probably more so less on the nuclear side and more on the AI side and dealing with our relationship with our own technology," Cameron said.
"And how we do really stand the possibility of making ourselves obsolete?"
The 1991 release - a sequel to the 1984 original - starred Arnold Schwarzenegger, Edward Furlong, Linda Hamilton and Robert Patrick. It followed Sarah Connor and her 10-year-old son John fleeing an advanced shapeshifting Terminator sent back in time to kill them.
Schwarzenegger's less advanced Terminator was also sent back in time to protect the pair. The film featured a scene in which Sarah Connor imagines a nuclear blast consuming Los Angeles.
"I tend to be kind of an apocalyptic kind of guy. I look at all the worst case outcomes," said Cameron, who said he started writing the film before the Berlin Wall came down and the collapse of the Soviet Union.
"I think that it's we have to be on guard and constantly aware. So whether it's climate change, or whether it's the threat of an AI potentially replacing us or rapidly altering our word in a negative outcome for humans or weather it's nuclear warfare - these are things we need to be constantly vigilant about."
According to Gizmodo, Cameron used CGI to change just one thing about the film - a continuity error over a broken car windshield. "It just bugged me," he told Entertainment Tonight.
As for any film reboot of the series, Cameron said the idea was being discussed but he wanted to make sure it had "fresh imagery, fresh characters" and wasn't "mired in the past".
The director said any reboot must "feel like a new, 21st-century version of a Terminator story but still stay true to what that means."
