Has Casting for Eustace Begun?

Rumors have been circulating around movie websites for the past couple of weeks that casting for Eustace has begun. The latest comment from a user on IMDb states, “Casting for Eustace began last week, with dozens of boys. Boys are just being filmed now and next week as well so I suspect the next round will start in 2 to 3 weeks.” NarniaWeb has not yet confirmed with the production that casting for Eustace has begun, but with Voyage of the Dawn Treader to start filming in January, it is certainly possible that the hunt for Eustace is on.
