Los Angeles Times speaks with the Phelps twins

There's another Harry Potter and the Half-Blood Prince interview posted today by The Los Angeles Times as they continue their series of Potter interviews leading up to the release. Today's interview is with the Phelps twins:

MG: What was your favorite experience working on “Half-Blood Prince?”

OP: That would be being a part of the Fred and George joke shop scene. The crew built an exquisite set and there are a lot of special effects involved to simulate the magical pops and explosions. It’s a great scene.
JP: I really enjoyed working with the crew. Most of my actual acting I was able to complete in about two weeks. When I wasn’t acting I would help the crew set up scenes and shots. I learned a lot more about direction and filmmaking in general and that was pretty cool.
