The summer movie season is almost upon us and one of the films that will be fighting for the box office crown is "The Twilight Saga: Eclipse."

Directed by David Slade, the third installment of the "Twilight" franchise continues the romantic triangle between Bella (Kristen Stewart), Edward (Robert Pattinson) and Jacob (Taylor Lautner) that solidified in last year's blockbuster "New Moon."  This time around, however, that villainous and evil vampire Victoria (Bryce Dallas Howard replacing fan favorite Rachele LeFevre) is forging an army to take down the Cullens and pretty little Bella.  Can Jacob and Edward protect her?

The thriller's latest trailer debuted on The Oprah Winfrey Show today, with none other than star Dakota Fanning there to introduce it, but Summit Entertainment has now released it online for everyone to enjoy.

"The Twilight Saga: Eclipse" opens nationwide on June 30.
