Director Roland Emmerich and co-writer and producer Dean Devlin have been developing the sequel for a few years without Will Smith in it.
According to Deadline, “Smith informed the studio that he won’t be joining in on a sequel that the filmmakers hope to have in theaters for July 4th weekend, 2016.”
Without Will Smith Independence Day 2 won’t be the same it’s like God Father without Marlon Brando.
