2. 'Men in Black III'
After a sequel to the original 1997 film was released in 2002, a third installment languished in development. But it's currently scheduled for release on May 25, with actors Will Smith and Tommy Lee Jones reprising their roles as alien-fighting Agents J and K, respectively, and Emma Thompson coming on board as Agent O. Agent J must go back in time to stop an alien from killing Agent K, meeting the younger version of his partner (played by Josh Brolin) along the way.
