Don't look for Robert Pattinson
to play a future Han Solo or Indiana Jones
star, 28, shot down any rumors Thursday as he walked the red carpet in Los Angeles at the Regency Bruin Theatre for the U.S. premiere of his latest film, The Rover
"I don't know why. Why is that coming out?" he said of speculation he could play a future Indy. "I honestly don't understand what it's all about. Man, I wish!"
He was equally clueless about reports that he was set to take on a younger version of the character Harrison Ford
made famous in Star Wars
"I didn't even know there was a Han Solo spinoff coming out," Pattinson, clad in an aqua Alexander McQueen suit, told reporters at the Loft & Bear-sponsored event. "Sounds like a cool spinoff. I'll watch it."
Pattinson was more talkative about his role
in the David Michôd-directed dystopian Australian outback thriller, in which he plays Rey, a Southerner from America, who is picked up and bullied by a violent drifter named Eric (Guy Pearce
The bleak crime thriller, set 10 years after a global economic collapse, marks a huge departure from his star turn as Edward Cullen
, where he was all hunky vampire heartthrob.
Michôd noted that he went with instinct in casting Pattinson as Rey. "I had this feeling about him, and sure enough when he came in, within five minutes I knew that I had found the guy that I wanted to play the character," he said.
Pattinson isn't sure how the film will be received but said he is hopeful. He called the script "strikingly original" and noted a "profound connection" when he first read it.
"I am very curious to see how American audiences are going to take it," he said of his latest role. "I am eager to see the reactions … I don't have any expectations of any movie that I do. I hope that people like it. I like it."
The London-born Pattinson
said he worked on a Southern accent for the film and he joked that he's still perfecting it. "I keep trying to do it in my real life. But nobody can understand what you are saying – like my real accent – so you get away with a lot!" he said, laughing. "Well, with my accent at least!"
opens in wide release on June 20.
