The Thaw is a 2009 American science fiction horror thriller film directed by Mark A. Lewis and starring Val Kilmer, Martha MacIsaac, and Aaron Ashmore.

The film begins with a video documentary by Dr. David Kruipen (Val Kilmer), a research scientist on Banks Island, in the Canadian Arctic and the outbreak of a pandemic, with 400 dead and 10,000 infected.

This is followed by a flashback to when David, his assistant Jane (Anne Marie DeLuise) and two other researchers tranquilize a polar bear, then discover the frozen remains of a woolly mammoth.

David calls his daughter Evelyn (Martha MacIsaac) and pleads with her to visit the research station.

Meanwhile, a group of students, Ling (Steph Song), Federico (Kyle Schmid) and Atom (Aaron Ashmore), are selected to join David's research team; Evelyn decides to come.

Bart discovers that the amputation was useless as his upper arm is now showing signs of infection; he opts to stay behind with Ling.

As the helicopter starts flying away, Evelyn shoots at it, causing it to crash into a building previously doused in gasoline.

Scott "Foywonder" Foy of Dread Central gave the film 2 out of 5 knives, claiming it "appears to borrow a tremendous amount of its plot from The X-Files.
