The duo is reuniting to make a follow-up which will be set "some years after the first film concluded," according to a press release.
The statement went on to explain that Scott and Fancher had planned the initial film to be a trilogy, similar to the Star Wars franchise.
Bosses at production company Alcon Entertainment insist, "It is a perfect opportunity to reunite Ridley with Hampton on this new project, one in fact inspired by their own personal collaboration, a classic of cinema if there ever was one."
Fancher adapted the Philip K. Dick story Do Androids Dream of Electric Sheep? to make the 1982 cult hit starring Harrison Ford as an expert on artificial humans.
