The Crazies (also known as Code Name: Trixie) is a 1973 American science fiction horror film written and directed by George A. Romero.

It stars Lane Carroll, Will McMillan, and Harold Wayne Jones as residents of a small American town that accidentally become afflicted by a military biological weapon.

David's pregnant girlfriend, a nurse named Judy, is called to the office of Dr. Brookmyre, where the two children of the arsonist are being treated for burns.

Days earlier, an Army plane carrying a bioweapon had crash-landed near the town, infecting the water supply with a virus code-named "Trixie," which is highly contagious and causes victims to either die or become hysterical and homicidally insane.

After spending the night hiding in a country club, the group attempts to escape through the nearby woods, eluding soldiers both on the ground and in an overhead helicopter.

Depressed and distraught by his experiences in Evans City, Colonel Peckem is ordered to relocate to Louisville, where symptoms of the virus have been reported.

Romero revealed that the military subplot was only featured in the first act of the script, and the rest of the film focused on the survivors and their attempts to cope with what was happening.

He stated that Hessel made a true attempt to adequately market the film, including releasing it under a variety of titles in different parts of the country, but that it never managed to catch the public's eye.

The website's critical consensus reads, "The Crazies isn't top-shelf Romero, but its blend of genre thrills and social subtext should still be enough to satisfy discerning horror fans.
