What is the title of the film "Olympus Has Fallen?"

"It's like 'Die Hard' but at the White House," a studio executive probably said about "Olympus Has Fallen."

Why is it called an angel has fallen?The title Angel Has Fallen can be misleading at the same time.Most people think it's a reference to the official aircraft of the President, the Air Force One, but it is actually about Banning himself, as he is the "guardian angel".

'London Has Fallen' is a sequel and a surprise follow-up to 'Olympus'.

The film will be released in the U.S. on March 22, 2013.
