“Globetrotting, gun toting, car chases, explosions: Dante Lam’s The Viral Factor has all the action-junkie goods and then some, including the most jaw-dropping scenes of plummeting in recent Hong Kong stunt choreography.”



“The film’s jittery opening 15-minute siege, set in Jordan, evokes Ridley Scott’s Black Hawk Down, while later passages recall the visual schemes of contemporary cop movies like Heat and We Own the Night.”



“The Viral Factor is explosively infectious. It may be the year’s best Asian action movie.”
