This blog has a strange article on a Miss Elliette (the Coco Chanel of American fashion…apparently) movie being in development.
At first it sounds like they’re kinda fantasy casting it themselves but later on they say:
Okay, everything above is totally true; the casting has yet to be confirmed. Natalie Portman may also play the title role.
Sounded iffy but I mailed some sources and they were quite quick to shoot it down.
Later I’ll add it to the lowest level of the rumoured projects page, but I think this link is a work of fantasy.
