Will Smith and Tommy Lee Jones reprise their roles as Agents J and K in this third instalment of the sci-fi action comedy. Agent J (Smith) has long been every bit as perplexed by the perpetually-surly countenance of his older partner, Agent K (Jones), as he has been by the variety of aliens the pair are charged with keeping under control. However, when alien forces assassinate K with such extraterrestrial efficiency Agent J seems to be the only person to believe that K hasn't been dead for 40 years, the younger man is at a loss and determines to get his partner back. With the aid of a terrifying 'time jump', Agent J travels back to MIB's early years in the 1960s. Here he hooks up with a younger Agent K (Josh Brolin) and attempts to prevent his death and change the course of history. Will he also learn a thing or two about the secrets of the universe the older K kept so close to his chest?

Three years on from the previous blockbuster, Marvel comic book character Spider-Man returns in his latest adventure. Peter Parker (Tobey Maguire) and his girl Mary-Jane (Kirsten Dunst) are on the cusp of contentment - but not for long. His ex-friend Harry (James Franco), son of the Green Goblin of the first film, becomes the New Goblin in his desire for revenge against Spider-Man. Fugitive Flint Marko (Thomas Haden Church), killer of Peter's Uncle Ben, has been transformed into the shape-shifting Sandman, possibly Spider-Man's toughest foe so far. To complicate matters further, a parasitic alien symbiote has attached itself to Peter's suit, giving him even greater powers but also bringing out the evil side of his personality. He has to struggle not only against two major adversaries but also against himself.
