Production sources on the Remember Me
set say Pattinson regularly attracts mobs of fans when they are filming. "It's been nonstop busy all day with people trying to get a glimpse of him, and the crowd goes nuts when they do see him," an eyewitness told PEOPLE Tuesday.
As a result, the actor has hired his own security in addition to the bodyguards provided by Summit Entertainment, according to the source, who adds that the heartthrob maintains a positive attitude about his fans.
"I think he appreciates it. He's not one to make a big deal about it. He's a chill guy and quiet so far," the source says. "I think he finds it a little weird that people are standing outside all day to get a glimpse of him, but grateful."
Neither Summit Entertainment nor a rep for Pattinson was immediately available for comment.
