James and Oliver Phelps, Rupert Grint talk fame, filming, and their future with The Guardian

In another set of interviews, this time with The Guardian, the Phelps twins and Rupert Grint share stories of meeting people in the street, auditioning for new roles and experiences they've shared on set.

Of note, James and Oliver Phelps spoke on how it was decided which twin would be George Weasley and which one would be Fred:

Even when it came to casting them, there seems to have been a temptation to see them as one unit. At first read-through of the script on set, James and Oliver still didn't know which Weasley they would be. "The casting director said, 'You're kidding, right?'," says Oliver. "She went over to speak to Chris Columbus (the director) and J.K. Rowling. I like to think there was a lengthy discussion about who was who, but she came back and said: 'James, you're Fred; Oliver you're George."

Also, Rupert shares his insight on the years of filming the 'Potter' series, from casting through to the final days on set. Rupert spoke of that emotional day, saying:

"At first," he says. "And I wasn't expecting to. But.." He lets himself think about it. "It was when I saw Dan crying." He shakes his head. "Then it really hit me. I'd never seen him that upset. It was just really, really raw."
