While the Royal wedding for Prince Williams and Catherine Middleton may have garnered a lot of attention this past April, the REAL marital celebration of the year for millions of people will be that of Bella Swan (Kristen Stewart) and her immortal vampiric lover Edward Cullen (Robert Pattinson) in this fall’s The Twilight Saga: Breaking Dawn – Part 1.

The official teaser trailer has been unveiled for the penultimate entry in Summit’s Twilight movie series, which promises to feature all the ham-fisted romantic atmosphere (with some delivery, this time) that fans of the franchise love – set against the luxurious tropical backdrop of Rio de Janeiro, where Bella and Edward spend their honeymoon.

As the Breaking Dawn movie synopsis puts it, Bella and Edward “finally give in to their passions” on their honeymoon – and it’s thereafter that things start to get a little weird. Fans of author Stephenie Meyer’s source material are more than aware of the bizarre complications that arise during Bella’s resulting pregnancy, including the gruesome deed Edward must perform in order to save the life of both his wife and unborn child.

Franchise staple screenwriter Melissa Rosenberg has already made it perfectly clear that most of said graphic moments will occur off-screen in Breaking Dawn – a cinematic equivalent to how Meyer shifts from Bella’s perspective to that of Jacob Black (Taylor Lautner) during the pivotal birth sequence in the original novel.

However, before all that goes down, Bella and Edward get to enjoy their simple but luxurious wedding and honeymoon together. So those of you expecting Part 1 of Breaking Dawn to be all about supernatural horror and gore need not apply.

Check out  the Twilight Saga: Breaking Dawn – Part 1 teaser trailer:

Oscar-winner Bill Condon (Gods and Monsters, Dreamgirls) took over the directorial reigns on both halves of Breaking Dawn, but – judging by the trailer – he hasn’t drastically altered the visual style from the last two Twilight flicks (New Moon and Eclipse). Given that Condon recruited a highly decorated creative team to help bring this supernatural romance franchise finale to life, there’s little reason to doubt that Breaking Dawn – Part 1 won’t look or sound as impressive as any other upcoming tentpole picture.

It’s the content, not the style, that distinguishes the first half of Breaking Dawn from just about every other blockbuster-in-the-making on the horizon. Case in point: most people associate dramatic choir trailer music with footage of mind-blowing CGI effects and awe-inspiring set pieces (see: the theatrical previews for Transformers: Dark of the Moon and Harry Potter and the Deathly Hallows: Part 2). So seeing that kind of musical accompaniment with scenes of wedding invitations being sent out, Bella and Edward spooning beneath a tropical waterfall, Jacob ripping off his shirt in the rain, Bella discovering her unnatural pregnancy – and everything else in the Breaking Dawn trailer will definitely prompt laughter from people not already deeply invested in the Twilight series.

Obviously, at this point, you’re either pumped to see the Twilight finale – or you really could not care less. So fans at least can take comfort in knowing that Condon and his filmmaking team look to do justice to the original Breaking Dawn novel (and all that implies).

The Twilight Saga: Breaking Dawn – Part 1 hits theaters on November 18th, 2011. Part 2 will arrive a year later on November 16th.
