I didn't read about the supposed connection between Julia and Angelique in the spoiler topic because, believe it or not, I still haven't even gotten around to reading most of that topic.
I definitely read it in a magazine or on a reputable Web site - possibly both - around the time that the first photos and articles began to show up in '11 - probably around September/October or so - and quite possibly in Entertainment Weekly and/or its Web site and/or Empire and/or its Web site. Places that were getting their info directly from the production of the film.
As for the spoilers, if they really are that bizarre, I suppose I really need to read them sooner rather than later - if for nothing else than for the good laughs they're likely to produce.
