Disney execs have told Carrie Fisher and Mark Hamill to slim down in preparation for their return to the 'Star Wars' saga.
It's been no secret that the stars, as well as Harrison Ford, would return to their iconic roles for J.J. Abrams 'Episode VII', which starts shooting early next year in the UK.
The film's producers are keen for 56 and 61-year-olds to look as close as possible to the characters of Luke Skywalker and Princess Leia, who they last played 30 years ago.
A source told The Sun: "Mark and Carrie need to be as close to their appearance in the earlier movies as possible."
Film executives at Disney and LucasFilm have used the considerable funds set aside for the enormous blockbuster to send the pair nutritionists and trainers.
"Producers are keen to help out and have offered support," continued the source. "The budget is huge so there will be no expense spared."
Harrison Ford, who will play Han Solo once more in the film, has not been sent a trainer, either because he doesn't need one or because Disney couldn't find one brave enough to face the notorious grump.
Pre-production on the project, which will follow the story written by 'Toy Story 3' scribe Michael Arndt, has already begun with preparations already being made for the film to start shooting at Pinewood Studios in early 2014.
'Star Wars: Episode VII' will hit cinema screens in the summer of 2015.
