Mark Hamill thinks the late Carrie Fisher is "simply irreplaceable".<br /><br /><br /><br />The 'Star Wars: The Force Awakens' actor admits it is "bittersweet" starring in the franchise without having Carrie alongside him.<br /><br /><br /><br />He wrote on Twitter: "It's bittersweet facing my final chapter without her. She is simply irreplaceable. I'm finding solace in the fact that she won't BE replaced & would love the worldwide outpouring of affection from those who loved her when they heard the news. #CarrieOnForever"<br /><br /><br /><br />It was recently revealed that Carrie will be featured in 'Star Wars: Episode IX'.<br /><br />The use of Carrie's unreleased scenes comes after Disney and Lucasfilm insisted early last year they wouldn't be using CGI to recreate her likeness for the upcoming movie.<br /><br />
