Here are some points to look out for: -Many of the actors in this movie sound exactly like they are speaking a language they do not understand and are just delivering nonsensical syllables, just like an alien would speak if mimicking human English speech. (the credits try to make you believe this is because it was made in Romania, but they didn't fool me.)
-Oppositely, the main boy-character speaks *perfect* English, but is so devoid of any emotion whilst simultaneously having beyond- human-child-level memorization and delivery skills that he must be an alien himself.
-The female lead is obviously a holographic materialization of a random 'Seventeen' magazine model, chosen by the aliens to represent the 'ideal' American teenage human girls' appearance, thereby helping make the movie popular. This is proven by the fact >that she has absolutely no intelligence whatsoever, a common characteristic of holograms.
-Just watch that preacher-man-thing. Hands down alien.
-The sheriff, too.
-In fact, I really think that the kid who plays 'Johnny Cole' or whatever is the only human who was in the movie, and had no idea that everyone else was an alien. Most likely he was a rejected character from the Nickelodeon show 'Hey Dude'.
-Finally, the actual 'aliens' that appear in the movie are simply far too realistic to be anything other than real aliens. It's impossible that human beings could create such realistic alien technology and costumes, therefore... real aliens. Heck, go buy it. It's a groundbreaking historical document!
