TV Guide is running a piece of Carrie Fisher where they drop this Star Wars Episode VII blurb:
As for the next Star Wars film, Fisher says she, Harrison Ford and Mark Hamill are expected to report to work in March or April. “I’d like to wear my old [cinnamon buns] hairstyle again — but with white hair,” she says. “I think that would be funny.”
That information doesn’t entirely fit with what Abrams said that filming begins in May. Or does it? They could report in April for costume fittings and film in May.
The TV Guide tone is rather assuring our Episode IV heroes are returning. Hopefully the information is from Fisher and not just an assumption on the part of William Keck at TV Guide.
