Take a deep breath before you watch “The Bourne Ultimatum” because, for nearly two hours, you’ll be holding it. From its opening shot to its final reel, the concluding chapter in this genre-redefining spy trilogy dives into the summer’s best action and thrills, only occasionally coming up for air to raise some hard-hitting questions and address some urgent, topical issues.

Up until the one-hour mark, the paranormal thriller “1408” delivers scares, low-key laughs and just the right amount of thought-provoking material. Then the picture gets all philosophical on us and collapses under the weight of its own ambition.

Writer-director Andrea Arnold’s harrowing and provocative thriller “Red Road” does a sly job of subverting audience expectation and manipulating our identification with the picture’s principal players.

The true story of a massive in-house investigation and sting operation that led to the pre-9/11 2001 capture of a spy within the United States Federal Bureau of Investigation turns into the informative and concisely told but only occasionally suspenseful thriller “Breach.”

Actors Anthony Hopkins and Ryan Gosling burn up the screen in their handful of scenes together as opponents in the courtroom, but otherwise the legal thriller “Fracture” fizzles more than sizzles.

South Korean pop idol Rain, billed here as Jeong Ji-hun, could have taken the easy way out and chosen a light, breezy romantic comedy to make his big-screen debut in — but he goes one better and costars in “I'm a Cyborg, but That's OK,” a light, breezy affair that, in an instant, turns dark and violently disturbing.

The intense psychological drama-turned-thriller “Enduring Love” opens with one of the year's most hallucinatory and haunting sequences. From there, it explores big themes of love, identity and the ties — sometimes literal — that bind one human being to another before it unravels into a standard stalker flick, complete with obligatory coda in which we learn the psycho killer lives to menace another day.

The zombies from “28 Days Later” get a new breath of life in the sequel “28 Weeks Later,” a modest but precision-tuned thriller that mixes scares and a macabre sense of humor with just a smidgen of thought-provoking and topical material.
