The Iceland Review has a short article detailing local Icelandic actor Jon Pall Eyjolfsson, who recently traveled to England to audition for a role in Half-Blood Prince
>"Everything is in a very sensitive stage but it is certainly exciting and it would be great if I get the role. I have met the people who are behind this film and I have read from the script. At this stage you only get to see parts of the script and there is a lot of secrecy about this whole thing."
Eyjolfsson has already been invited back for another audition round, and he will know in May whether or not he got the yet-to-be-revealed role (rumored to be Young Voldemort/Tom Riddle). Read more details here
