Although he was disappointed with the movie in general, he couldn’t seem to say enough good things about Tom Felton’s performance! He raved:
“I will however say – and I HAVE to say this because it is extremely important to me in my opinion: Tom Felton as Draco Malfoy was unbelievable. I can safely say that he stole the show. He stole every single scene that he was in. He was outstanding. I could not believe how great he was in this movie. He really did steal every single scene he was in. I think he deserves all the credit for that. He really was excellent.”
His comments about Tom start at about 1:50.
