Once again, Will Smith and Tommy Lee Jones star as agents J and  K, government employees who police the many alien beings living amongst us on earth. Only this time, Jones doesn’t get much screen time because the plot centers on a diabolical alien who travels back to the 1960s to assassinate his character.  In order to set things right, agent J also travels to the past, meeting a younger version of K (Josh Brolin) in the process.
