In a interview with the magazine, Hamill said, "I'm selfishly mad that she's not here to make me laugh. But I'm also grateful for all that she was able to give us while she was here. It has not been easy."
In the same interview, franchise newcomer John Boyega, who plays Finn in the franchise joked that he failed his diet because Carrie had told him to "take some chocolate bars" from her stash in the fridge.
He said, "I was on a strict diet during 'Episode VIII', and she was like, 'Kid, get into that fridge and take some chocolate bars. I have many there.' And I did. I failed my diet because Carrie Fisher told me to. And it [felt] great."
The eighth installment, 'The Last Jedi', in the epic sci-fi franchise 'Star Wars' will hit theatres on December 15.
