Eclipse is the third movie in the Twilight Saga series to be adapted for the big screen, coming just eight months after the release of New Moon.

The movie follows a string of mysterious killings which is gripping Seattle. Bella, whose high school graduation is fast approaching, is forced to choose between her love for vampire Edward and her friendship with werewolf Jacob.
And Stewart admits that her first kiss with co-star Taylor Lautner, who plays Jacob. was a little awkward.
