Every major film blockbuster needs a wailing baby. Fact. Where would the movie Titanic be without a crying baby interrupting the most famous piece of dialogue from it? Or for that matter, where would 300 be? Or Jerry Maguire and even Gandalf?

Yes, some classic movies are made infinitely more cry baby-tastic with the insertion of a crying baby. Waaaaaah! Waaaaaaaaaah!
