This is a rather brilliant video I came across which shows what it would be like if A-list Hollywood directors did John McCain's attack ads (unlikely considering most of them are probably for Obama, but we can still imagine).

The first is by John Woo, where the only flaw is that John McCain is not played by Nicholas Cage, the second is an barely coherent Clerks style rant from Kevin Smith, and the last is a genius Wes Anderson parody. 

Enjoy.
