"My favourite Harry Potter was the Goblet of Fire because it's quite funny and it's so tense. When you watch it you don't know what will happen next!"
"My favourite Harry Potter film is definitely Harry Potter and the Goblet of Fire. I love it because the Dark Lord becomes reborn and that is where the adventure starts. I also love the Triwizard tournament."
"My favourite has to be Harry Potter and the Order of the Phoenix. I love the bit when Fred and George Weasley use all those fireworks. It's amazing!"
"My favourite film was part 2 because I was in it!"
"I like Deathly Hallows Part 1... mainly because at the end of the movie it builds up the tension for Part 2."
"My favourite is the Chamber of Secrets as it was cool to see that Lord Voldemort was very similar to Harry when he was at Hogwarts. They both got into mischief and were always curious about the school."
"My favourite one is Harry Potter and the Order of the Phoenix because of the battle at the end with the Order vs the Death Eaters in the Department of Mysteries."
"I like the Order of the Phoenix best because I think the acting is brill and you see them being independent. Also the scene at the end at the ministry is great. It's so sad!"
"I especially liked The Prisoner of Azkaban because of the Marauder's Map, Professor Lupin and Buckbeak the hippogriff."
"I think the Goblet of Fire was the best because it had a lot of action - dragon fighting, the mermaids, the maze and Voldemort."
"It has to be the Prisoner of Azkaban because they introduced a new spell and the dementors. GREAT MOVIE!"
"My favourite is Harry Potter and the Prisoner of Azkaban because it was dark and edgy and it had time travel!"
"My favourite one was The Prisoner of Azkaban because we first met Sirius Black then. I also liked the Goblet of Fire because we see the Quidditch World Cup and Viktor Krum."
"I can't belive that it's all ending, but the best Harry Potter film for me would have to be Harry Potter and the Goblet of Fire because it was filled with action from the start. I can't wait to see Harry Potter and the Deathly Hallows Part 2. It's going to be amazing!"
"My favourite film is The Prisoner Of Azkaban beacuse I liked the plot and the way the film was made."

"I love all the Harry Potter films... It's too hard to choose!"
"I like the first one the best! It was the most fun and had many light-hearted moments in it. The others are good as well, but they are much darker."
