Evolution is a 2001 American comedy movie directed by Ivan Reitman (Ghostbusters). A meteorite lands in the middle of the Arizona desert. On it, extraterrestrial single-celled organisms cavort, which should earn their discoverers Ira Kane and Harry Block - two small-town teachers - the Nobel Prize. But then the extraterrestrial creatures mutate at breathtaking speed into man-killing monsters. Now Ira and Harry must stop the threat as quickly as possible. They are supported by a clumsy alien researcher and a clumsy firefighter candidate. The cast also inludes Ethan Suplee, Michael Bower, Ty Burrell, Gregory Itzin, and Sarah Silverman.
The following weapons were used in the film Evolution:
Ira Kane (David Duchovny) uses a Winchester 1300 with an extended magazine tube to kill the alien dinosaur in the mall. Wayne Gray (Seann William Scott) appears to use a newer Defender model of the Winchester. Interestingly enough, the film's DVD cover reverses the shotguns used by Scott and Bloom (Bloom wields Scott's 1300 Defender, while Scott wields Bloom's Mossberg 500).
Standing in for the M9, Beretta 92FS pistols are carried and used by the US Army Military personnel guarding the meteor crash site. After Lt. Cryer (Ashley Clark) is killed by one of the alien primates, Wayne (Seann William Scott) picks up his pistol and uses it to kill the primate.
Browning M2HB Heavy Machine Guns are mounted on Humvees, tanks, and M35A2 "Deuce-And-A-Half" trucks are also seen used during the assault near the end of the film.
