Fake breasts were once the in-thing among celebs, but now even Hollywood has started to actively prohibit them.
In a recent casting notice seeking extras for the fourth instalment of Pirates of the Caribbean, Hollywood clearly specified that actresses "must have real breasts. Do not submit if you have implants."
It went on to explain that there would be a "show and tell" boob-veracity test that involved, among other things, running.
"I think the Pirates' story is indicative of a larger trend in Hollywood," the New York Post quoted one female casting agent, who has been working on movies and TV shows for nearly two decades, as saying.
"Large implants, in my opinion, take the projects and the actors to a sleazier level. They become a joke," she said.
Agent Megan Foley, who has cast more than 3,000 commercials and, most recently, a James Brolin film, sees a change coming. "I do see a trend of bodies going more natural," Foley said.
"About 10 years ago, I worked on Blow with Ted Demme, and [no implants] was the main requirement for the girls. And trust me, back then, it was a tall order!" Foley added.
Danny Roth is another casting agent on the no-boob-job bandwagon. One of his latest films, Open House, opens at Tribeca next week, featuring an "implant-free" cast including Anna Paquin, Rachel Blanchard and Tricia Helfer.
"If you're talented, let your talent speak for you," Roth, who has offices in New York and LA, said.
"Rachel, our lead, has definitely relied just on talent. She's not well endowed.
"Personally, I think implants are indicative of something else, potentially. Insecurity, or that they're taking advice from people they shouldn't be taking advice from," he stated.
