This is it, guys.

This is the end.

Tomorrow, the final Twilight film will be released in theaters, ending the saga of Edward and Bella for good. (Or at least until Stephenie Meyer decides it's time to purchase her own island and writes a sequel.) Will Breaking Dawn Part 2 live up to the other films in the series? Will it somehow surpass them to become the best of the franchise? Or will it be a total letdown?

As a general rule, sequels seldom surpass the original in terms of quality, and the final film in any series tends to be the last for a reason. (Usually, because it’s not good.) In honor of the culmination of the Twilight saga, let’s take a look back at other blockbuster film franchises and see whether or not the final installment lived up to expectations.

Let’s be honest – Emma Watson will probably always be known for her role as Hermione Granger in the Harry Potter franchise.

But in her new film The Perks of Being a Wallflower, she throws all her wizard tricks out the window for her character Sam, a free-spirited teenager dealing with the ups and downs of adolescence.

We chatted with Emma at the Wallflower premiere in Hollywood where she dished on what draws so many people into the film and, hypothetically, who she would play in a Harry Potter remake!

Who said writing wasn't a lucrative profession?!

Not only have some authors like Michael Crichton and Stephanie Meyers made a killing on their books like Jurassic Park and Twilight, they've even managed to sell the rights to their work to major film companies and make millions more while those movies go on to become billion dollar franchises!

In honor of Harry Potter author J.K. Rowling turning 47 today, here's our round-up of the 8 most successful contemporary authors-turned-movie-moguls! And we're sure that once the 50 Shades of Grey movie is made, EL James will be on this list too!
