Francis Lawrence (Constantine) directs this third big-screen version of Richard Matheson's classic 1954 sci-fi tale (after The Last Man on Earth in 1964 and The Omega Man in 1971). Will Smith gives a convincing performance as a military scientist who is immune to a virus that turned most of humanity into vampire-like zombies. He effectively puts across the paranoid loneliness and sense of hope in the face of despair of a man who could be the last surviving human on Earth. However, the flashbacks, with epic scenes of Manhattan in chaos, sit awkwardly next to Smith's attempts to cope with his isolation - such as conversing with shop dummies and working his way through every single DVD in the local rental shop. Some formulaic shocks, credibility-busting plot holes and unconvincing CGI monsters shift this apocalyptic chiller into B-movie territory. But there's still an eerie charge in seeing familiar landmarks like Times Square transformed into a desolate, overgrown wilderness.
