“Hellfire” (**1/2 out of four) was a modestly affecting crime melodrama about a drifter (Stephen Lang) who wanders into a nowheresville Midwestern town under the complete rule and authority of a ruthless mob boss (Harvey Keitel) and tries to help himself and the various other residents (Scottie Thompson, Michael Sirow, and others) escape. Leisurely story initially holds its grip thanks to Lang’s authority and quiet intensity but loses its way as it starts to simmer into a conventional action thriller and melodrama and starts to becomes a Coen Bros-like version of “Rambo.” Lang is rock-solid as usual; Keitel is wasted in his umpteenth role as a crime boss.
