Independence Day 3
Independence Day 3 was a planned third film in the Independence Day series and wasn't known to have an official title. It was announced by Roland Emmerich shortly after Independence Day: Resurgence was released in theaters.
Jake Morrison, Dylan Hiller, Patricia Whitmore, and Dr. David Levinson form an alliance to take down new aliens.
Why It Was Cancelled
- Independence Day: Resurgence received extremely negative reviews from critics and audiences alike.
- Independence Day: Resurgence failed at the box office.
- Sometime afterward, Disney merged with 20th Century Fox before cancelling the unsuccessful franchise.
- Dean Devlin decided not to make a third film following the poor reception and box office performance of Resurgence. However, Rolland Emmerich recently said that he has an idea for a third film. Despite all of that, there is still a highly unlikely chance there will be a third film. 
- Independence Day 3 was permanently cancelled.
