Rapaire...there may be 'one' exception. Have you seen "Survivorman"?...about the guy who is dropped off in some wilderness for a week and tries to make it back to civilazation?

They make the point that he carries the cameras and does all his own filming...which often becomes part of the script. I wouldn't be surprised if he didn't have some real 'emergency beacon' along, but he seems to do what they say he does.

(This is unlike "Bear Gryles"..or whatever his name is...who OBVIOUSLY has a camera crew following him)
