First look at a pregnant and dying Bella in brand new Breaking Dawn footage

Previously unseen footage of pregnant Bella Swan dying has finally been revealed to Twilight fans.
An extended theatrical trailer for Break Dawn: Part 1 was released today with the the scenes of sickly, frail Bella (Kristen Stewart) fighting for her life and her baby.
The dramatic two and a half minute trailer opens with Bella trying to calm her nerves before her walk down the aisle.

Clutching her father Charlie's arm, she says, 'Just don't let me fall Dad.'
She says her vows with Edward (Robert Pattinson) in a breathtaking setting, with the Cullen family proudly looking on.
Bella's happiness is stalled as a dishevelled and distraught Jacob arrives to say his final goodbye before Bella leaves as a married woman - soon to be transformed into a vampire.

The best friends are seen dancing alone in the dark as heartbroken Jacob tells her: 'This is how I'll remember you - pink cheeks, heartbeat. You'd think I'd be used to telling you goodbye by now.'
A brief glimpse of the newlyweds' blissful honeymoon and wedding night is shown.
Edward's strength breaks the bed frame in the throes of passion; he tells his wife the next morning that 'last night was the best night of my existence.'

But their honeymoon period is short lived before they discover Bella is pregnant with a half human, half vampire baby.
Bella's health rapidly deteriorates and she is shown looking deathly pale and thin as Dr Cullen informs her that her heart will give out before she can deliver her child.
As Bella fights to protect her baby and live long enough to deliver it healthily, the wolves hear of the unborn child and decide it is a threat.

Pack leader Sam is shown telling them: 'We don't know what they've bred, we have to protect the tribe before it's too late.'
Jacob defects to warn the Cullens that a war is coming for them. 'Bella will be slaughtered,' he tells them.
The nail-biting preview ends with Bella collapsing, and Edward and Jacob rushing to save her life and deliver the baby.
