Sergeant Gerry Boyle (Brendan Gleeson) of Galway is crass and abrasive and interprets the law a bit freely, all to glorious comic effect. Paired with strait-laced American FBI agent Wendell Everett (Don Cheadle), Boyle seeks to solve a couple of murders and disrupt a massive drug shipment in what could have been a trashy fish-out-of-water buddy comedy--but, through a combination of sharp and witty writing, ruthlessly speedy editing, and understated but spot-on performances, "The Guard" is a marvel of character-based storytelling. Gleeson ("28 Days Later", "In Bruges") and Cheadle are peerless actors, the kind who rarely star in blockbusters but who bring dynamic life to any scene they're in. The supporting cast is chock-full of off-kilter talent, turning even the most incidental role into a memorable character. Writer-director John Michael McDonagh makes a remarkably accomplished feature debut; "The Guard" moves forward with gripping efficiency, yet every moment seems casual and often beside the point, crammed with colorful language, incidental comedy, and a deliciously eclectic soundtrack. The result is hugely entertaining. One of the best films of 2011. "--Bret Fetzer"
