There are just 26 days to go until Breaking Dawn: Part II is here! Robert Pattinson has officially kicked off the countdown with the promotional tour in Syndey, Australia.

Australia is the first country that they're promoting the movie in, and Rob's taking over. Later, Kristen Stewart will be heading to Japan and Taylor Lautner will go to Brazil.

Rob posed for some photos with this fans, and he talked about the hardest scene to shoot - the final battle scene!

"We were shooting this big action sequence for about two and a half months in a massive warehouse where they normally sell cows, with a bunch of fake paper snow and green walls, and you literally started to go insane after a while! Yeah, it gets tough doing stuff like that, it gets a bit repetitive."

He also talked about Kristen's major transformation in the last movie:

"She was really excited about being a vampire. Everybody else who'd been pretty consistently in the movies, they'd obviously been playing a vampire like every day for ages. And so it's funny seeing someone suddenly come into it and try and figure out their own version of the physicality and the mentality of it."

Breaking Dawn: Part II will arrive in theaters worldwide on November 16th! Check out a new promotional video below:
