Boom mic visible at the top of the screen when the Roses and the Hutchinsons first meet with Elena to complain about both couples being on the island together.
During the trial on the beach scene, just as the Hutchinsons sit down on the stand, and right before Elena says, "Let's start with Exhibit A", a furry gray boom mic briefly dips into the top of the frame.
Boom mic briefly seen again right after Mr. Rose says "Objection!" and the shot changes back to the Hutchinsons on the stand holding the "wand" twig.
