Jackson Rathbone who plays Jasper Hale in the Twilight Saga Movies including Eclipse is recently caught up in an interview by MTV as he tells Bella about his past life before he met the Cullens as he will be having a large role in the Eclipse Movie as he is the only vampire among the Cullens who know how to combat the new born army of Victoria.
"It was just really fantastic to get to delve in there and to get to don all the Civil War regalia and whatnot. That was a pleasure," he said. "I had to wear this wool suit of a major, cavalry major. "I got the big hat and everything. Hop off the horse, bow to these ladies, and then I get eaten. And then I get turned!"
As the film goes Jasper will tell his story to Bella that seems to be longer conversation as what we see till here, where Jasper will be helping the Cullens prepare for to combat the newborn vampires of Vitoria. As we all know that it is Jasper who can handle this responsibility as will be seen on a flashback of Jasper training newborn vampires while he's still "a bad dude, a bad vampire."
