Rob Marshall, director of the fourth Pirates of the Caribbean movie Pirates of the Caribbean: On Stranger Tides, has issued a request asking only for actresses without breast enlargements to audition for the film.

The trilogy thus far has been immensely successful and has featured many women clad in tight bodices. However the call for actresses for the latest installment has said they are looking for, “Beautiful female fit models. Must be 5ft 7in-5ft 8in, size 4 or 6, no bigger or smaller. Age 18-25. Must have a lean dancer body. Must have real breasts. Do not submit if you have implants.”

Although many breast implants are now made to look convincingly natural, Marshall has warned that they are planning a ‘show and tell’ day where applicants will be asked to pass a test specifically aimed at rooting out those who have had implants. It is not yet know what sort of test has been devised.
