FULL STORY:  Buzzfeed put together a list of 25 interesting facts about 2000s pop culture.  Here are the highlights:

1.  “Hey Ya” by Outkast is actually a SAD song.  It’s about how people stay in relationships when they’re unhappy, because it’s better than being alone.

2.  YouTube was meant to be a VIDEO DATING SITE when it launched in 2005.

3.  Scottish actor Dougray Scott was originally cast as Wolverine in “X-Men”.  When he had to back out, it was offered to Russell Crowe.  Russell turned it down, but recommended Hugh Jackman.

4.  “Arrested Development” and “The O.C.” almost did a crossover episode.  But the producers of the show ultimately decided it was too “meta”.

5.  Mark Ruffalo almost dropped out of “13 Going on 30” because he had such a hard time during rehearsals for the “Thriller” dance scene.

6.  Fans thought Heath Ledger was a TERRIBLE choice to play the Joker in “The Dark Knight”.  It’s a lot like how people thought Michael Keaton was an awful choice to play Batman in 1989.

In both instances, the haters were DEAD WRONG.

7.  In 2006, “A History of Violence” became the last major Hollywood movie to be released on VHS.

8.  Amy Winehouse was tapped to sing the theme song for the 2008 James Bond flick “Quantum of Solace”, but she was a WRECK by that point.  Jack White was brought in last-minute, and recorded “Another Way to Die” with Alicia Keys.

9.  “Queer Eye for the Straight Guy” was born when the creators saw a wife berate her husband for not being as well-dressed as three nearby gay men.

10.  Even though it was a major Hollywood film about fashion, “The Devil Wears Prada” only had a $100,000 wardrobe budget.
