Based on Robert Ludlum´s novel, The Hades Factor puts a bio-terrorism spin on a good old-fashioned spy thriller storyline for this tense TV miniseries. Stephen Dorff is top-billed as a former spy turned medical researcher who is pulled back into the espionage business when a new and mysterious disease erupts simultaneously in three military-sensitive regions. The target of the investigation centers on another covert operative (Mira Sorvino), who made off with a black-market virus in the middle of a government sting. The film´s solid cast, which includes Blair Underwood and two Hustons--Danny and Anjelica (as the U.S. President)--helps the suspension of belief required for this sort of story considerably, and director Mick Jackson delivers the required amount of action at a brisk and engaging clip. Squeamish viewers should know that the outbreak scenes are particularly grisly for a television production.
