Twilight - Breaking Dawn: Part 1
Release date: 18 November 2011
Running time: TBC
Director: Bill Condon
Starring: Kristen Stewart, Robert Pattinson & Taylor Lautner.
The film centres around the marriage of Bella (Kristen Stewart) and Edward (Robert Pattinson) and how their happiness is halted by a series of betrayals.
Whilst Bella and Edward are in Rio de Janeiro for their honeymoon, Bella discovers that she's pregnant. During a near fatal childbirth, Edward eventually gives into her wish and becomes immortal.
However, the unexpected arrival of their extraordinary daughter, Renesmee, sparks an epic battle between the Cullens and the Volturi, the equivalent to the vampire Royal family.
Romance and suspense are in full force once again as the action-packed tale is continued with the same passion and fantasy that's made the Saga such a worldwide phenomenon.

You should see it because: Oscar-winning director Bill Condon has reportedly read the book twice and watched the previous movies over and over to make sure it's up to scratch.
