Star Wars' Domhnall Gleeson reflects on major Hux twist
"We had talked a little bit about it," Gleeson recalled, "but I think JJ [Abrams, director] was keen that whoever took over the second film have room to do what they wanted with the second film, and then when he made the decision to come back for the third film obviously the same was true." "I don't think Rian [Johnson, The Last Jedi director] had any preconceived notions about exactly where it needed to go. It was just leaving room for it to go somewhere interesting, which I think is what JJ did." Lucasfilm
