Roland Emmerich has said the sequel will take place 20 years after the first film and sees the aliens return with reinforcements.
Emmerich spoke about the fact Will Smith will not be back for the sequel.
We have like maybe half of the people that you know would know from the first film (in the script) and the other half people who are new.
Bill Pullman will be back as the former President of the United States.
The sequel will be will be the first of a two part story, tentatively titled “ID Forever, Part I” and “Part II.”
