The latest Star Wars VII story comes from the reliable Hollywood Reporter where they are reporting the reason Michael Arndt was taken off writing duties for Star Wars VII was because of a difference of opinion on the central emphasise of characters.
Michael Arndt split as writer on Episode VII in the fall, with duties taken up by Abrams and Lawrence Kasdan, who co-wrote Episode V: The Empire Strikes Back and Raiders of the Lost Ark.
According to multiple insiders, the reason for the parting of ways was not due to a timeframe issue, as has been reported, but rather due to a difference of opinion of which characters to emphasize.
Arndt is said to have focused on the offspring of Luke Skywalker (Mark Hamill), Han Solo (Harrison Ford) and Princess Leia (Carrie Fisher), with the original trilogy’s heroes taking on supporting roles. Abrams, however, wanted Episode VII to focus on the classic trio of characters, so audiences could have one more chance to enjoy them before a fitting send-off. The new characters, the offspring, will now be in supporting roles, according to these sources, and take center stage in Episode VIII and IX. Some characters have disappeared from the Arndt script and new ones are being added.
Star Wars creator George Lucas, who directed the 1977 original and each of the most recent trilogy, was also involved in the debate, according to insiders. But Lucas, who sold his Lucasfilm to Disney in 2012, acquiesced to Abrams and producer Kathleen Kennedy, who now runs Lucasfilm.
