“Above Suspicion” (**1/2 out of four) was a well-crafted but improbable melodrama about a rookie F.B.I. agent (Jack Huston) about to make a drug bust in Kentucky of a multi-tentacled dealer (Johnny Knoxville) and falls in love and begins an affair with his drug-addled informant (Emilia Clarke) but once she finds out he’s married and that she’s pregnant- this leads to even more stormy passions and murder. Director Phillip Noyce and Elliott Davis do a first-rate job of recreating the sultry atmosphere of beautiful Kentucky locations but Huston’s character’s actions and motivations simply are not believable at times and weaken the proceedings, even if this is based on a true story novel by Joe Sharkey. Clarke’s sensational Oscar-caliber performance galvanizes the film, however, and makes this still worth seeing.
