On his personal site, actor Chris Rankin revealed today that he doesn't think his character Percy Weasley will be appearing in Harry Potter and the Goblet of Fire.
His latest contract included Prisoner of Azkaban "+ 1," meaning one more film, but not necessarily the next one:
Having been speaking to my agent about why I've not heard anything from Warner Brothers re: Goblet of Fire, they've been making some enquiries into the legal side of not being used on the film, when I've been contracted to it... Turns out that my contract states that I was contracted to appear in Prisoner of Azkaban +1 more HP film - it doesn't have to be the next in the series (as we'd all presumed) - what this basically means is that we're unlikely to be seeing Percy in Goblet of Fire, but that doesn't mean that he won't be in another film along the lines of the series...
Rankin added that he's content to work on his own projects for the time being. His twenty-first birthday is in October, and he's also coming to the U.S. next month.
Percy plays a much bigger role in Order of the Phoenix, the fifth in JK Rowling's book series.
