When Chris is screening the raw footage of the plane crash, it is already completely edited with multiple camera angles and shot with various lenses, even though only one camera was supposedly used to film it, and the footage is supposed to be raw.
When Chris is in the native voodoo "chicken man" costume neither Bill or Alma notice that his arms are white, even though he is waving them around right in front of them.
There would not be any electricity in the jungle to run the bright, powerful projector used by Chris to intimidate the natives.
