Cold Blood is an icebound thriller about a retired assassin (Jean Reno) living in the frozen North. A snowmobile accident places a woman under his care, and soon he is forced back into action when some bad guys come looking for her. Briskly paced and atmospheric, this potboiler is formulaic but sure to satisfy fans of the stoic lead actor, who has built a career playing the sort of stone-cold killer you can root for. François Guétary directed, with the Carpathian mountains doubling as the North American wilderness.
