Thanks to TomFeltonFansGermany for uploading this clip from ITN of their report on the DVD treatment Harry Potter and the Half-Blood Prince has received.
In the clip we see snid-bits of Tom from the DVD itself, most notably from Behind the Cameras with James Phelps, before we are treated to the interview wherein Tom discusses how the cast became more involved this time around.
A quote:
Tom Felton who plays Draco Malfoy said: “We had special effects, stunts and props. It was the first time that they’d ever come to us and said ‘look we want to shoot something really substantial for the DVD. We want to really go behind the scenes and not just do a little tour, we want all the cast to be involved’.
He added: “We spent a couple of months going round, we were passing cameras back and forth. We had a great time”.
