When designing a presidential limo for White House Down, producers were stuck with a bit of a conundrum: The specifications of the actual, heavily-armored presidential limo—nicknamed The Beast—are kept under wraps by the Secret Service for security reasons. How was a production team to replicate a vehicle that, apart from pictures, they had no actual information about?

According to this behind-the-scenes featurette about the film, it was all guesswork. Much of the replica had to be built based on scaling a 2009 Cadillac Escalade headlight, and by simply looking at pictures of the real Beast. The result turned out to be massive, custom-built replica of the real presidential limo that can't actually take a missile, but really looks like it could. This is Hollywood, of course - looks are everything.
