Its been long rumored that there was an Independence Day sequel in the works. But those were just rumors. More or less those rumors were fan based or fan pleads to Fox for one. Fox on the other hand has been exploring the possibility of a sequel and has made bids in the past that an Independence Day 2 was possible. Well not only is it possible it probably will be and the rumor mill has now churned into the direction of fact. Looks like Will Smith has signed a 2 movie contract that will be shot back to back .
