The 60-year-old actress may have passed away last Christmas, but she has and always will be Princess Leia to fans.
Having embodied the role for 40 years, Fisher took part in hundreds of fan events.
Now fellow Star Wars The Last Jedi actor Driver has revealed her advice to him as a new cast member of such a popular franchise.
Speaking with GQ, the actor explained what Fisher said to him at the Lucasfilm panel during San Diego Comic Con 2015.
Driver said: “You have, also, the hidden identity of this princess who’s hiding who she really is so she can survive and Kylo Ren and her hiding behind these artifices.”
With Driver calling Rey a princess, could this mean that she is in fact Leia’s daughter and Kylo Ren’s sister?
Star Wars 8 The Last Jedi will be released in UK cinemas on December 14, 2017.
