Just got back from the 2012 movie (SPOILER ALERT)

The Museum Curator? who was blown up in the same tunnel as Princess Diana died in (with reference to the Queen later on in the Movie.)

Aswell as the Vice-Presidents plane coming down near Pittsburg (same as on 9/11.)

Then the President saying he would be the last Black President of the US (or words to that effect) before the White House was evacuated, which would tie in with the next US Election polls if Obama was still in office in 2012.
