12 Movies That Cleverly Gave Away Their Twists Early

8. Alfred's Accidental Gag - The Dark Knight

The Twist

When the Joker kidnaps Rachel Dawes and Harvey Dent and forces Batman to choose which one he wants to save, he actually swtiches the addresses he gives the Dark Knight, knowing that he will try and save Dawes, in order to bring about Dent's (and Batman's) fall.

Batman unwittingly ends up saving Dent and Dawes dies.

The Reveal

It turns out her death was foreshadowed well before Sal Maroni's men kidnapped her and Dent, by a brief exchange between the virtuous DA and Alfred:

Harvey Dent: You've known Rachel her entire life, haven't you?

Alfred: [laughs] Well, not yet sir!

It's subtle, but it's a clever one to catch when you know what happens at the end.
