Robert Pattinson, Twilight Alum, Doesn't Know How to Play "Normal Guy," Reads Reviews About His Films

Actor best known for playing vampire Edward Cullen plays a human in his newest film, The Rover

Robert Pattinson, who as vampire Edward Cullen, made Kristen Stewart and millions of Twilight fans swoon and helped the film franchise rake in more than $3.3 billion worldwide, has a hard time sinking his teeth into a particular kind of role: a normal guy.

In his newest movie, The Rover, the 28-year-old British actor portrays Rey, the brother of a car thief, who is kidnapped by a guy whose vehicle was stolen. The film is set in a post-apocalyptic Australia, also stars Guy Pearce and hit theaters on Friday, June 20. This the first non-vampire project for Pattinson since the 2012 release of the fifth and final Twilight film, Breaking Dawn Part 2.

"I think lots of people want to do stuff that's relatable, and I want to do stuff that's unrelatable," Pattinson told The Huffington Post in a recent interview. "I don't think I have particularly normal emotional reactions to things. So trying to play someone who is just a normal guy...I don't really know how to do it."

Pattinson, who recently debunked rumors about playing Indiana Jones, has portrayed a human before—he romanced Reese Witherspoon in the 2011 romantic drama movie Water for Elephants, portrayed a womanizing Parisian in Bel Ami, alongside Uma Thurman and Christina Ricci and took on the role of an American billionaire in Cosmopolis.

What may be helping to instill doubts about his "normal" acting abilities may be the reviews of his movies, which Pattinson says he reads.

"I don't quite know why," he told The Huffington Post in a recent interview. "It's so difficult to figure out if you're doing the right thing. I guess there's some way of knowing after reading, sort of. But sometimes it's just incredible how opposite everything can be. It's bizarre. You learn absolutely nothing after, and you just hate bad reviews. You can't even remember the good ones."

As of Friday afternoon, The Rover is tracking as 66 percent "fresh" on film review website Rotten Tomatoes. So how did more of Pattinson's past movies fare?

The highest-rated film featuring Pattinson is the 2005 film Harry Potter and the Goblet of Fire, the fourth movie in the hit eight-part series that made more than $7.7 billion worldwide. The critics' reviews aggregated on Rotten Tomatoes garnered the movie, in which the actor had a relatively small, but important role as a hunky young wizard named Cedric Diggory, a rating of 88 percent (so fresh).

The Twilight Saga: Breaking Dawn Part 2 was rated 48 percent (rotten)—just one percent less than the highest-rated Twilight movies, the original 2008 film and the third, Twilight Eclipse. Cosmopolis—64 precent. Bel Ami was considered a dud among critics, with 28 percent. Water for Elephants received a rating of 60 percent "fresh" and took in more than $117 million in global box office earnings.

Pearce told E! News earlier this month that Pattinson is "really great" and "vulnerable" in The Rover.

 "It's such a heartbreaking performance I think," the actor said.
