You can tell that a scene was chopped between the owl delivering the letter and Harry's foster family getting into the car with Petunia looking very upset. I was unhappy at the choppiness of the editing. I think the movie was originally closer to two hours, but the director was ordered to make cuts to bring it to 2:18 to be able to squeeze in more showings/day and increase profits
Did you mean closer to three hours?
...and...
Does this mean we might be able to look forward to a longer "Directors Cut" DVD?
