Evolution (2001)

Continuity mistake: During the scene in the mall when the girl is in the dressing room, she keeps putting on more layers of clothing. But as they are shooting different shots she will have a hot pink shirt on, then it is back on the hanger, and then back on again. It switches back and forth many times. (01:00:50)

Other mistake: At the very beginning of the movie, when the guy throws the match into the house, it doesn't enter through the window. The match crashes and bounces back, but the fire inside the house still occurs. (00:02:40)

Factual error: At the end of the film, when Duchovny and Jones are on the ladder truck shooting the head and shoulders, they are yelling "go go go". They slide down the ladder and the next shot is the fire truck speeding away. Movie elapsed time 5 seconds. It is a physical impossibility for a fully extended ladder to be lowered, retracted and bedded in a span of less than 4-7 minutes. Even if the hydraulic lines are cut, the ladder would remain upright and not collapse/retract. (01:32:59)

Trivia: "Evolution" was originally written as a serious sci-fi thriller by writer Don Jakoby. When Ivan Reitman signed on to direct, he felt the concept would make for a good ensemble comedy, similar to his film "Ghostbusters." Jakoby actually liked the idea of reworking the film into a comedy so much, he stayed with the project and assisted in re-writes.

Trivia: In the scene where David And Orlando lead the class into the crater to see the meteor on the field trip if you pay attention to the background actors you can see a young John Cho. (Harold from Harold and Kumar).

Trivia: During the shoot in Arizona, Dan Aykroyd would have fun by randomly show up at the houses of locals to hang out and have a cup of coffee. He also helped out at local businesses.

Brigadier Gen. Russell Woodman: No need to play the blame game here, Allison. No harm, no foul. Suffice it to say that we're all very appreciative of the discovery made by Dr. Kane and Mr. Black.
Harry Block: Block.

Harry Block: Hey, beneath this calm, sexy exterior beats the heart of a true scientist.

Dr. Allison Reed: At this rate, they will take over Glen Canyon in three days. In a week, the rest of Arizona. Within two months, the United States will officially belong to them. And we are extinct.
Governor Lewis: Oh, you gotta be shittin' me.
