Harry Potter and the Order of Phoenix has a lot (a lot a lot) of differences between the movie and the book… this is the second part…

During Care of Magical Creatures class, Hagrid tells the class about Threstrals. There Harry and Neville both see the Threstrals. In the movie, Luna’s the one who show’s Harry the animals and Neville never acknowledges them.

In the book, Harry witness the attack on Arthur Weasley and when he wakes up, Neville goes to get McGonagall, who takes him and Ron to Dumbledore’s office. There, the Weasleys’ and Harry all take the Portkey back to Grimmauld Place. In the movie, however, Harry has his first Occlumency lesson with Snape right after the attack, while in the novel he learns about the lessons during Christmas break, with Sirius. Sirius and Snape exchange words…

In the movie, all scenes regarding St. Mungo’s are omitted. The re-appearance of Gilderoy Lockhart and appearance of Neville’s parents are also omitted. In the book, Harry finds out about the condition of Neville’s parents from Albus Dumbledore significantly before Neville’s other friends learn of it. In the film, Sirius tells Harry how they suffered a fate worse than death, and Neville later tells Harry more in the Room of Requirement.

After Christmas, the Weasleys, Harry and Hermione return to the school on The Knight Bus, which is not featured in the film.

Harry’s date with Cho Chang in Hogsmeade is omitted and their relationship is largely played down.

Rita Skeeter was also omitted from the film. In the book, Hermione blackmails her into writing articles that support Harry as the rest of the Wizarding world denies his claims, as well as him being sent dozens of mail.

In the film, Hagrid mentioned that the reason for the Centaur’s anger towards humans was because the Ministry of Magic was taking away their lands. In truth, it was because Firenze had taken up the post of Divination teacher, and the centaurs were angry that he was giving away their secrets to his students, combined with the fact that Grawp was living in the forest and was disturbing their habitat.

In the book, Dobby goes to the room of requirement to tell Harry that Umbridge and her Inquisitorial Squad are coming, while in the movie they find out when they are breaking the wall.

In the novel, Dumbledore’s Army is discovered because Marietta Edgecombe, a member and a friend of Cho Chang, tattled to Umbridge. In the film, Cho is duped into revealing the truth via Veritaserum, and Umbridge and the Inquisitorial Squad break into the Room of Requirement. Also, in the film, this is used as a reason for her and Harry’s break-up.

Dumbledore’s escape is slightly different. He is aided by Kingsley, who alters Marietta’s memories, and knocks out everyone in the room out except for Harry and McGonagall. The line: “You know, Minister, I disagree with Dumbledore on several points, but you can’t deny, he’s got style.” is said by Phineas Nigellus Black.

In the book, Harry sees Snape being harassed by James and Sirius via Snape’s Pensieve, while in the film, Harry casts a shield against Snape’s Legilimency spell and sees Snape’s memories. Also, in the film, it is only James that bullies Snape while Sirius just watches amusedly.

In the book, members of the Inquisitorial Squad had additional powers such as docking points even from Prefects.

Dolores Umbridge tries to slip Veritaserum into Harry Potter’s drink and asks him in turn where Albus Dumbledore and Sirius Black are. This is where he learns that her fireplace is the only one not being watched.

Harry’s career advice session is omitted. This would contradict the next film, as Harry mentions being told he needed an O in his Potions O.W.L. to continue.

In the book, Umbridge and McGonagall row about how she punishes students during Harry’s career guidance meeting and also have a minor disagreement during class inspections. In the film, McGonagall’s class inspection is sadly completely omitted.

The Weasley twins’ prank last a lot longer, with a lot of things going on all around the school (and they’re never on their broomsticks, which are locked in Umbridge’s office) and they started it to allow Harry to use the Floo network to talk to Sirius and Lupin. They only flee when cornered by Umbridge. Fred and George Weasley’s famous Portable Swamp is omitted from the film.

Grawp is portrayed as very gentle, whilst in the book he is very violent and even strikes his half-brother Hagrid in the face during his appearance.

In the book Harry and Hermione were introduced to Grawp by Hagrid while the school was distracted by the Quidditch final of Gryffindor vs. Ravenclaw, in which Ron was playing.

In the book, Cornelius Fudge’s Aurors and Dolores Umbridge try to take Hagrid away, and as a result, Professor McGonagall gets hit by four stunning spells and gets taken to St Mungos.

In the book, several weeks elapse between the Weasley twins leaving, and the O.W.L. Exams where Harry sees the vision of Sirius being tortured at the Ministry of Magic during the exams. In the film, these occur one after the other, on the same day, along with Harry, Ron, and Hermione getting caught by Umbridge trying to use her Floo Network connection.

Kreacher tricks Harry into thinking that Sirius is in the Ministry, propping Harry to get there.

Umbridge reveals to Harry and his friends that she is the one who sent the Dementors to Harry discreetly without Fudge’s knowledge as a way to discredit him.

They fly in pairs on the threstals, given that only Harry, Luna and Neville can see them.

In the Department of Mysteries, they go through a lot of rooms before getting to the Hall of Prophecy which were omitted in the movie. Also, Death Eaters Apparition is different. During the Battle of the Department of Mysteries, Hermione gets critically injured by a curse from Antonin Dolohov, Ron is attacked by disembodied brains in the Thought Chamber, Ginny Weasley’s ankle is broken, Neville Longbottom’s nose and wand are broken, Luna Lovegood gets knocked out while attempting to perform Colloportus, and Tonks, Moody, and Kingsley Shacklebolt are injured in duels.

The Levicorpus spell is only introduced in the next book… so was the non-verbal spells for the golden trio.

Bellatrix doesn’t kill Sirius with the killing curse, she hits him with some other curse and his body falls through the veil in the Death Chamber.

Sirius never calls Harry by the name “James”. It’s only implied earlier that he views Harry in the same way he saw James.

In the book, Dumbledore uses the Fountain of Magical Brethren to protect Harry while dueling Voldemort, and Fawkes takes a Killing Curse for him. Bellatrix is trapped under a statue from the fountain until Voldemort Disapparates with her.

In the book, Harry frees himself from Voldemort’s possession due to his grief over his godfather’s death, but in the film, he frees himself from Voldemort’s possession due to the strong love he feels for his friends and Sirius.

After Voldemort flees, Dumbledore shouts at Fudge for not believing in him for a year.

In the book, Harry Potter loses his temper with Dumbledore after Sirius Black’s death and smashes his possessions, which did not happen in the film. Dumbledore also explains about the prophecy and shows Harry his memory of Trelawney making the prophecy.

After Sirius death, Harry asks Nearly Headless Nick if he could came back, and Nick explains that not all wizards can come back as ghosts, and most wouldn’t want to.

Draco Malfoy’s new found hatred for Harry Potter due to his father’s arrest has been omitted , so the scene where Harry tries to curse Malfoy, Snape takes 10 points from Gryffindor and McGonagall returns to Hogwarts and awards Gryffindor 250 points and Ravenclaw 50 points for the battle in the Department of Mysteries is also omitted. Draco’s attempt to attack Harry Potter on the Hogwarts Express with Crabbe and Goyle to get revenge for their fathers’ arrests, only to be stopped by the members of Dumbledore’s Army is omitted.

When they get to King’s Cross, the members of the Order of Phoenix have a talk to the Dursleys about Harry… this, unfortunately, never happens in the movie.
