Robert Pattinson Compares 'Breaking Dawn' Birth Scene to What?!

Fans flocked to theaters this weekend to see The Twilight Saga: Breaking Dawn — Part 1, but according to star Robert Pattinson, some Twi-hards might not have gotten exactly what they expected in the fourth installation of the tween phenomenon.

During an interview with the UK's Press Association, R-Pattz compared the highly anticipated birth scene of his onscreen daughter (by way of his offscreen girlfriend, Kristen Stewart) to something a little unexpected.

"We kind of shot it as an R-rated horror thing," Rob explained, "And then just kind of edited out the really gruesome bits."

"If you went on the set it didn't look — it looked like a Saw movie. It didn't look like a Twilight movie at all."

For those not familiar with Saw, the most it has in common with Twilight is probably the fact that it is also a highly succesful franchise. Other than that, the two couldn't be more different.

Instead of focusing on a supernatural-infused teen love triangle, Saw focuses on the deranged madman Jigsaw, who murders his victims by testing their will to live through highly complex torture devices and "games."

Hmm...for some reason we think the two series might have very different demographics.
