Pattinson commented that Twilight is different from other horror series because vampires are presented as being realistically seductive.
The actor told Parade: "I don't think I've ever seen a vampire movie where I think the vampires are attractive. OK, girls are sometimes kind of sexy, but guys end up looking worse than they do in their real life with the pale make-up and the fangs.
"I've watched True Blood and all those guys are great-looking, but you put vampire make-up on them and they look less handsome on the show than they do in reality."
Pattinson also revealed that he's begun to ponder what life after Twilight will be like.
"I feel like I've kind of been in a whirlwind for so long, even though I've done other movies in between," he added. "Whenever you promote something, they always want you to talk about Twilight, so it's kind of constant. I am living a life which I didn't really know existed. You can kind of delay being an adult for quite a while."
Pattinson previously revealed that he worries if his career will survive when The Twilight Saga comes to an end.
Breaking Dawn - Part 1 is released in cinemas worldwide from November 18.
