Corrected entry: In the movie, they use "Head and Shoulders" as the key ingredient for the defeat of the aliens, being as "Head and Shoulders" key ingredient was selenium. "Head and Shoulders" does not contain any selenium.
Corrected entry: When the team goes into the cavern to douse the alien with Head and Shoulders shampoo, they drag the firehose very far into the cave. They then have to quickly run out and it is easy to see that they have left the firehose rolled into the cave. When they drive away, the firehose is not seen dragging behind them and when they are ready to use the firehose in the final scene, it is magically coiled on the back of the truck waiting for them.

Corrected entry: Evolution takes place in Arizona over Thanksgiving break, and it's obviously cold since the trees are bare and you can see the actors' breaths in many scenes. But why is Seann William Scott picking up towels poolside and people in bathing suits are sitting around the pool? Is it cold enough to see your breath but still warm enough to sunbathe?
Corrected entry: During one of the final scenes in a laboratory, some of the characters are talking about finding 500 gallons of selenium to help stop this evolution. When they ask, "Where are we going to find 500 gallons of Selenium at 2 o'clock in the morning?" there is sunlight coming through the trees outside the window. (01:20:52)
Corrected entry: When the green dragon is flying through the shopping market, you would expect people to be running and screaming in all directions. But if you look in the background in a lot of the shots people are walking calmly and one woman is even continuing to pay for her items as if nothing has happened.
Corrected entry: When David Duchovny analyses the blue goo with his computer, a nice bar graph is shown which says that there are 10 base pairs or proteine used in the genetic code. However, for this to happen, a programmer would have had to have written this functionality into the program - what programmer would include this feature if it's completely inconceivable? (00:14:00)
Corrected entry: Throughout the film, Duchovny calls the splitting of the alien organisms to form 2 identical ones 'mitosis.' This is not the correct term. Mitosis refers to the replication of material at a cellular level, and happens in all living organisms. Since they are multicellular creatures, they are having 'fission' reactions, which is the creation of 2 identical creatures, like for example hydra. A former government scientist and professor should know the difference. It is basic biology.
Corrected entry: I find it hard to believe that the Governor of Arizona (Dan Aykroyd) would have final say in ordering the US Army to napalm a portion of his state. That is a case of state government going over federal government, which is unconstitutional. The President would probably be the only one who could make that decision.
