Hope for Dumbledore?

I heard a rumor that Michael Gambon may have actually looked at the sixth book of the Harry Potter series, HP and the Half-Blood Prince, while filming the movie. Notice that I didn't say he read the book, only looked at it. Apparently Daniel Radcliff who plays Harry Potter said at one time or another that they were consulting the book during some scene they were filming together. This is just a rumor I heard. I have not found the actual quote.

Any glimpse whatsoever at any of the books could only help Michael Gambon and his horribly inaccurate portrayal of Albus Dumbledore. If there was anyone who ever needed to consult the source material it's him. I don't understand what his problem is. He's a British actor so he obviously has tremendous talent. The books are neither too simple to be interesting nor too complex to follow. I can only conclude that he is lazy and belligerent and in it for the money since he clearly puts no thought whatsoever into the character he's portraying.

I'm not going to set any expectations of a better performance, but I will hope that Daniel Radcliff loaned him the book for a day or two peruse. We'll see in November.
