If you don't like the Twilight franchise, you're best off clicking away now. If you do like the Twilight franchise, then prepare to feast your eyes on this 79 second teaser trailer for The Twilight Saga: Breaking Dawn Part 2.
Revealing quite a few beats from the plot, it manages to keep the little 'un, Renesmee (Mackenzie Foy), largely under wraps whilst piling on plenty of build-up shots to a climax between the Volturi and the rest of the gang.
See, the Volturi hear, from Maggie Grace's Irina, that the Cullens have an "immortal child", and it's against vampire law to turn children into vampires. So the Volturi and all their allies come a-calling to get rid of Renesmee, while Bella, Edward and co. gather in allies to, first, convince them that the youngest member of the family is a human hybrid and, secondly, stop them slaughtering first and asking questions later.
Quite how director Bill Condon is going to negotiate the book's more out-there moments remains to be seen, but one thing's for sure: this teaser trailer is going to get a lot of people very excited indeed.
The Twilight Saga - Breaking Dawn Part 2 hits cinemas on November 16 this year.
