Revealing mistake: The spiders advancing on Harry and Ron during the visit to Aragog are not the same in appearance. In some of the closeups a few have elongated bodies, while others are medium-sized. And many of them look quite aged, like Aragog himself.

Revealing mistake: Mrs. Weasley might as well knit like a muggle because she's not making any progress with magical knitting. In the Weasley's home and we see the magic knitting, the needle shoves into the hole, but no thread loops around and it is not advancing. The amount that has already been knitted is magic indeed since all the motion shown in the film produces no results. (00:11:25)
Lucius Malfoy: Let's hope that Harry Potter will always be around to save the day.
Harry Potter: Don't worry, I will be.
Trivia: The first scenes in the movie are some of the last scenes filmed. Viewers kind of tell by the way the actors' voices and looks changed. For example, Matthew Lewis (who played Neville Longbottom) said that he had to stuff cotton balls in his cheeks in the "Mandrakes in the Greenhouse" scene, since he had lost so much weight since the beginning of filming.
Question: Does any one know the Japanese golfer joke Uncle Vernon was telling at the beginning of the movie?





Answer: The joke goes like this, "A California business man, while in Japan for some business meetings and a few rounds of golf, arrived in Tokyo a day earlier than expected. Feeling lonely that evening, he employed the services of a beautiful young Japanese girl to be his companion for the evening. Although the Japanese girl spoke very little English and the businessman spoke no Japanese, their passion roared and in the heat of the moment she began yelling "Machigatta ana. Machigatta ana" Hearing this, the Californian believed he had pleased his female Japanese friend and soon afterwards went to sleep. The next day while playing golf with his Japanese business colleague, his Japanese partner holed his shot from 170 yards away. Wanting to impress his friend, the Californian began yelling, "Machigatta ana!" The Japanese business man turned to the Californian and with a confused look on his face asked, "What do you mean wrong hole?"
