Independence Day (part 2 and 3?)

Apparently Producer/Director of ID4 is talking sequel!

According to the latest issue of Entertainment Weekly, the aliens are coming back to Earth (twenty years after the first attack) after a distress call goes out back to the alien's homeworld. Of course, now Earth has been rebuilt using some of the alien's technology. Actor Bill Pullman who played the President (and fighter pilot commander) almost 17 years ago in the first movie has confirmed that he will be back but at this time Will Smith has not committed. Are you ready for two more sequel of ID4?

Here's the link to EW article.
