Revealing mistake: When the smudge pot is set off, it's on the ground, smoke coming of the ends. A moment later, along with a huge cloud, if you look at the bottom of the scene, there's an area about five feet wide billowing smoke.

Revealing mistake: When Manfriedi and Johnson are in the tunnel at the beginning, the second one has a lighter going to light the way. Trouble is, there is no way that the little flame could light the area as it did. Also, the lighter couldn't have provided light to cast its own shadow inside an area that perfectly round, thereby revealing that it was lit with a light close to the camera.
