Very well-done movie based on the true story about a U.S. Customs official who goes deep undercover to infiltrate the Medillin Colombian drug trafficking empire.  Bryan Cranston is top-notch as agent Bob Mazur, who teams up with Emir Abreu, played by the always entertaining John Leguizamo,  Their goal to infiltrate the cartel’s money laundering operation is of course very dangerous and stressful.  This is a thinking man’s move,  with more dialogue than action. Even so, I was on the edge of my seat wondering if one small slip (involving a state-of-the-art briefcase) or a misplaced word (forgetting a detail of the fake identity) would cause the intricate sting operation to fall apart and cost Mazur, and his wife and children, their lives.  If you need lots of nonstop action, I would skip this movie.  However, if you want to see a great performance by Bryan Cranston and learn how Bob Mazur and company were able to pull off a two year sting that uncovered drug kingpin Pablo Escavar’s money laundering operation and led to the arrest and conviction of over 100 people, this movie is definitely worth seeing!
