With it he has become wealthy beyond measure and is a household name. But the downside, which he found out to his cost this summer, is just as consuming after he discovered, along with the rest of the world, girlfriend and co-star Kristen Stewart cheated on him.
But now as the Twilight series comes to an end and he has rekindled his romance with the sexy starlet, Robert is taking time to look back at the journey and told okmagazine.com that it hasn't all been fun and games.
"It's kind of fun to deal with the terror and the huge highs and lows of things," he said. "If I could get any semblance… it's not really anonymity… I think if I had a little bit more control over my public image I guess that would be nice."
"I'm still getting massive surprises every time we have a Twilight related event."
As the hit series, which has made the British hunk a worldwide name, comes to an end, Robert says he's overwhelmed with feelings about how to deal with it seeing as it's been his life for five years now.
"I've never felt more completely bewildered, knowing we only had a month left of Twilight stuff to do," the 26-year-old shared.
"I've said since the second one it's going to take ten years to settle into my brain so I'm four years into it."
And the Hollywood hunk had an interesting response when asked what advice he would give himself going back in time to when he started this incredible journey.
"Start drinking vodka instead of beer," he laughed. "And try to get a six pack as early as possible, and you'll be a much more successful actor."
As he goes forward in his career branching out from being a vampire, Robert said he is isn't "afraid of getting typecast."
"I don't know if people will accept me in [other roles] but there's really nothing to be afraid of," he added.
