Can Head & Shoulders shampoo save the world from a rapidly evolving alien invasion?
In short: In the 2001 sci-fi comedy Evolution, a meteor crash in Arizona unleashes extraterrestrial organisms that condense millions of years of development into mere hours. As the military fails to contain the threat, a team of scientists discovers that a common household toiletry might be the only weapon capable of stopping them.
Directed by Ivan Reitman, Evolution was envisioned as a modern successor to his hit Ghostbusters. The film follows college professor Ira Kane and geologist Harry Block as they investigate a meteor that secretes a strange blue liquid. This substance harbors microorganisms that evolve into complex life forms, including fungi, aquatic creatures, and reptilian predators, all of which adapt to Earth's oxygen-rich environment at an alarming rate.
The production faced significant creative shifts during development. Originally based on a story by Don Jakoby, the script underwent extensive rewrites by David Diamond and David Weissman, who incorporated elements from a separate screenplay about friends hunting aliens. While the original vision featured a battle of wits with an intelligent species, the final film opted for an action-heavy climax. The cast includes David Duchovny, who sought the role to pivot away from his iconic X-Files character, alongside Orlando Jones, Seann William Scott, and Julianne Moore.
The film's climax hinges on a bizarre scientific theory: because the aliens are nitrogen-based, selenium sulfide—the active ingredient in Head & Shoulders shampoo—acts as a lethal toxin. In a desperate maneuver, the protagonists inject the substance into a massive, fused creature via an enema, causing it to implode. Despite mixed critical reception and a modest box-office performance of $98.4 million against an $80 million budget, the film developed a lasting cult following and inspired an animated series, Alienators: Evolution Continues.
Technically, the film relied on extensive creature design, with Tippett Studio creating over 18 distinct alien species. Production spanned from October 2000 to February 2001, utilizing locations in Page, Arizona, and the Greater Los Angeles area. Today, ownership of the film rests with Paramount, which acquired the rights to DreamWorks' live-action library in 2006, marking a complex legacy for a movie that began as a simple tale of extraterrestrial biology gone wrong.
