A casting call for Disney's upcoming Pirates of the Caribbean 4 specifies that women with artificially enhanced breasts will not be considered for a role. According to the New York Post, interested parties will even be subject to a "jiggle" test to ensure their assets are real. What does Disney have against silicone?

This sound enlightened, but likely isn't: We love the idea of blacklisting plastic-surgery addicts, says Donna Kaufman in iVillage. However, "we suspect that Disney's motives are less idealistic and more practical." Perhaps they "don't want the extras looking more voluptuous" than the film's small-busted star, Keira Knightly? "When we see a casting notice that specifies 'no Botox' ... that's when we'll celebrate progress."

Disney is begging for a lawsuit: This alleged "jiggle" test sounds cheesily pornographic, says Maureen O'Connor in Gawker. One wonders: Is there any way to "prove veracity of breasts" without "sexually harassing" their owner? The whole thing sounds like a waste of time, and a commercial misstep. After all, Americans appear to love breast implants.

This is business as usual in Hollywood: "Ridiculous" though it sounds, says Nicole Sperling in Entertainment Weekly, a silicon-breast ban is "not that uncommon." It's "actually standard practice" to require a natural figure — particularly for "period work" such as the Pirates movies. The same rule sometimes applies to guys with "ripped abs" or "bulging biceps" that would ring false in a pre-personal-trainer setting.
