The first casting call ad that appeared only mentioned SAG-AFTRA members. Project Casting has a casting call out that has expanded the search to SAG-AFTRA/Non-Union member. It’s not clear if that means they were always looking for both union and non-union extras or women who are willing to be scantily dressed on screen aren’t beating down their doors.
Regardless, if you look good in a black bikini, are a free spirit and want to make $250/8 hrs, the ad is here.
