Epoch is a 2001 science fiction film directed by Matt Codd, starring David Keith, Stephanie Niznik, Brian Thompson, and Shannon Lee.

Czaban (Stephanie Niznik) with the technical assistance of terminally ill engineer Mason Rand (David Keith), picked up on the Mexican border in time for the mission.

Fomented by NSA agent Allen Lysander (Ryan O'Neal), conflict explodes between the troops of the two factions and the Torus reacts, blanketing the planet with a thick cloud cover, evidently starting the process for a new mass extinction.

However, the Torus absorbs the blast and, seemingly satisfied by the extreme sacrifice attempted by the two scientists, ceases its actions, sheds its external shell and, in the form of an energy sphere, leaves Earth.

On November 24, 2001, the Sci Fi Channel's debut airing of Epoch garnered a 2.3 rating, or 1.7 million household, becoming the network's highest-rated original movie, surpassing the miniseries Frank Herbert's Dune (2000).
