Orange Skittles, I am fairly sure that Julia Roberts received a lot more money for Three Days of Rain than Bradley Cooper and Paul Rudd. I would also say that by the time they made American Hustle, Bradley was a much bigger box-office star than Jennifer Lawrence, having been a part of the Hangover franchise. Jennifer had not won her Oscar when American Hustle went into production, and her own Hunger Games franchise had not yet become the established success it became. Plus, she is a supporting player in American Hustle, and he is the lead.
Amy Adams having been paid so much less is indicative of disparity on first look, but she is more of a supporting player than a leading star. She has supporting roles in nearly every one of her hits. She is wonderful, and a multi-Oscar nominee, but it's been a while since she's been the main star and the movies in which she has been (Big Eyes and Trouble With the Curve, i.e.) have not been hits.
A more accurate barometer of sexism in the payroll could be determined by how people who did not have the track record of big box-office success or failure behind them are paid. Well-respected players who aren't stars -- Michael Shannon and Sarah Paulson, say.
Sienna, in any case, has been in two recent film hits (American Sniper and Foxcatcher) whose success she did not have that much to do with. They did more for her than she for them. And the minute she began performing in Cabaret it was back on TDF. I am not a producer, but if I were I would not see her as a top box-office draw.
