Fisher and Mark Hamill (who reprises his role as Luke Skywalker) reportedly lost a combined 85 pounds for their return to the Star Wars franchise. While the co-stars work well together, Fisher hinted that the characters they're playing might be at odds.
"[They're] probably sick of each other," Fisher said. "They're probably competitive: 'You have more Force than I do. What's with that?' Sibling rivalry: 'You had a better relationship with dad.'"
The seventh installment of the Star Wars saga also features Harrison Ford returning as Han Solo. While he didn't require any drastic weight transformations, Ford's body definitely took a toll during filming.
"I was standing in the doorway talking to [director] J.J. [Abrams], and I made a gesture to the right and the door came down and hit me in the midsection," Ford said. "It hit me with such force it flung my left leg up and it dislocated my left ankle and broke both bones in my leg."
