Will Smith will not be welcoming anyone back to Earth. On the other hand, parts of it will take place off-Earth.

Roland Emmerich, director and producer of the 1996 blockbuster Independence Day, seems practically giddy in these promotional photos for the upcoming sequel, Independence Day: Resurgence. I can imagine why; with the exception of Will Smith, he's reunited the core cast of the original film, including Jeff Goldblum, Bill Pullman, Judd Hirsch, and Vivica A Fox, for a sequel set 20 years after the "War of '96." (I would've gone with "The Big Alien War"...but I'm not a screenwriter.) He's also added Liam Hemsworth, Maika Monroe, Sela Ward, Jessie Usher, and Charlotte Gainsbourg.
