Joel McKinnon Miller, who plays Mr. Kaznyk (Charles' dad) in Super 8, had some wonderful things to say about Joel Courtney. From Matt J. Horn:
When you first start working with a young cast you’re not sure what to expect. It was clear from the beginning that these were some talented kids that showed up prepared and ready to work. Quite professional. The lead role of Joe is played by a young man named Joel Courtney. This was Joel’s first film and he is terrific. I’m sure you’ll be seeing a lot more of him as well as Elle Fanning in the near future.
