Visible crew/equipment: Opening credits (also a few minutes in) has a fiery spaceship crashing into the camera for this was a 3D movie. What's interesting is that a mirror can be seen on the left portion of the screen just before the collision. This was apparent at the theatres and on the VHS tape release. For some reason, the DVD release has it cropped out and now the spaceship is off-centered at the beginning (fortunately the bonus material still shows it).

Continuity: The opening narration says the season is late spring, or otherwise a warm season of the year in Arizona, yet many people are wearing wool suits, coats and long-sleeved shirts during the day. At one point, the sheriff's dialogue even discloses that it is 92 degrees (and no air conditioning).

Visible crew/equipment: The alien takes a stroll through the Arizona desert after crashing. The animals are frightened and run away with the exception of the owl. The bird has a string tied to its left leg and someone off camera yanks it, and the bird screeches and does a complete flip while flapping its wings. It looks hilarious - poor owl.
