Plot hole: Seventeen-year-old Jane knew they went to the house to "strip it" (cabinetry, hardware, etc). After removing a chandelier, Jane went into another room and, for no legitimate reason, used a sledgehammer and made a hole in the wall. There just happened to be a stash of money easily accessible via the hole, which was half-way up the wall. (00:26:14)
Continuity mistake: The window with broken blinds to the right of the hole in the wall turns into a green curtain for a couple seconds, then back to blinds. When Pablo is pulling the money out of the hole in the wall, the green curtain shows up next to it (a couple feet from where the window is located). [There is a tattered green curtain on the adjacent wall.]. (00:26:33 - 00:27:06)
Other mistake: The crate, which had gaps between the boards, was buried about 8-10' deep, but it was free of dirt when it was being hoisted out of the hole. (01:14:25)
