Speaking at the celebration of the epic space opera franchise in Florida, the 65-year-old star discussed the path his character could take in "The Last Jedi", The Independent.
"It's possible, anything is possible," he said.
The actor, however, quipped that he suffers from "short term memory loss" and said he "lost credibility with the public through social media because I lie all the time".
"And I post and exclusive look at the Episode VIII trailer and it's a trailer on the back lot... It's like the boy who cried wolf, nobody believes me," he added.
