Michaela Zee Ridley Scott is reflecting on his decision to step down from directing the “Blade Runner” sequel due to a scheduling conflict with 2017’s “Alien: Covenant.” “I shouldn’t have had to make that decision,” Scott said in a recent Empire interview. “But I had to. I should have done ‘Blade Runner 2.’” After being attached to the project, Scott announced in 2014 that he would no longer direct the “Blade Runner” sequel, instead choosing to helm the sci-fi horror film “Alien: Covenant,” starring Michael Fassbender, Katherine Waterston, Billy Crudup and Danny McBride.
