Visible crew/equipment: When John looks through the binoculars at the start, it reflects 2 big white squares which, considering they are in the jungle looking at a blue/rust coloured building, it appears to be part of the filming equipment. Perhaps a light screen? (00:06:20)
Answer: Using a mold, a realistic pregnancy belly is made of latex (rubber), including the distinct belly button, to suit the proportions of Emilie de Ravin who plays Claire. It is then painted with a special paint/adhesive compound that adheres to the surface and for shots of the actual belly, additional veining and stretch marks are airbrushed on.
