Bogie and Bacall, R.I.P. With one exception, the 15 U.S. films that have grossed the most worldwide are about wizards or superheroes or other wonderful weirdos, and the exception is "Titanic," and come on.

Same today, with zombies and monsters leading the box office. (Note to self: Pitch "Zombies and Monsters" next elevator ride with a Warner's suit.) But ka-ching, eh? Here are the 15 top-grossing U.S. movies of all time, arranged from No. 15 to No. 1 -- you know, for suspense.
