In 2005, Robert Pattinson portrayed as Cedric Diggory. Let's see what his Harry Potter co-stars have to say about his extreme popularity and success:

Now that Pattinson has entered a world in which bloodsuckers chill Stateside — and now that he must contend with Twilighters going wild for every bit of RPattz gossip out there — Daniel Radcliffe looks at his onetime “Potter” co-star’s career arc as educational.

“It’s really interesting for me, as somebody who is a central feature of a pretty huge franchise,” said Radcliffe, who returns as Harry Potter in the “Half-Blood Prince” on Wednesday (July 15). “It’s interesting to watch — because I haven’t seen ‘Twilight’ — and to suddenly be able to just watch another franchise go massive is really interesting.”

“Twilight” has given Radcliffe a chance to understand how an everyday fan must react to his own franchise. “I have no concept of what ‘Potter’ looks like to the rest of the world because I’m so involved in it,” he explained. “So to watch ‘Twilight’ kind of explode globally had been fascinating.”
