They were not included in deleted scenes either.

However, Peeves is featured in the video game versions of the films.

The following locations appear in the book but are not in the film (in order of appearance): Railview Hotel, the London Underground (included in a deleted scene), a hamburger restaurant near Paddington station, the greenhouse classrooms, the Gryffindor Quidditch changeroom, the staffroom and the Astronomy Tower.

Deleted Scenes
The following is a list of scenes that were not in the final cut of the movie but were included on the DVD as deleted scenes.
 * Dudley is trying on his Smeltings uniform when Harry walks in and asks if he will be wearing the same thing. Petunia and Vernon scoff at the thought of Harry attending Smeltings and Petunia shows him Dudley's old uniform being dyed and tells him it will be his uniform at the local state school.
 * Petunia cracks open eggs for breakfast but instead of yolks finds crumpled up letters from Hogwarts and shrieks at the sight of owls outside her window.
 * Hagrid and Harry are on the London Underground. Harry is studying his school item requirements reading it aloud. When he comes across dragon hide gloves, he asks Hagrid if they mean from a real dragon. Hagrid confirms this and explains how he would love a dragon of his own.
 * Harry, Ron and Hermione are walking down a corridor. Harry is thanking Hermione for getting them out of trouble (presumingly after the troll attack). Ron contradicts that they did save her life. At one point, Ron says "What are friends for?" Hermione looks pretty pleased when Ron says this.
 * In the Great Hall, all the other Hogwarts students that stayed for Christmas are eating at the top of the tables. Harry is further down the hall looking into the fire. Ron leaves the feast and goes down to Harry, offering to play chess or visit Hagrid. When Harry refuses these offers, Ron warns him not to return to the Mirror of Erised.
 * Harry, Ron and Hermione are in the Great Hall, Harry and Hermione studying for their final exams. Ron is going through his Chocolate Frog cards. Hermione warns Ron about studying for his exams when Neville limps in with his legs in a leg locker curse. Ron tells Neville that he must start standing up for himself. Seamus offers to do the countercurse, but Neville refuses as Seamus has gained a reputation for setting fire to things with all his spells. Seamus is insulted by this and points out he has magically regrown his eyebrows (probably after setting fire to them in Charms). However, as he turns and storms out, we see a big bald patch on the back of his head. Harry, after reading one of Ron's cards, alerts Ron that he has found Nicholas Flamel on Dumbledore's card. Hermione tells the other two to follow her (leaving Neville still leg locked).
 * This is the full version of Harry's first Potions lesson as it was in the book. This scene includes Harry's back remark about Hermione knowing the answer to the questions Snape asked him. Snape answers the questions he asked Harry and asks the rest of the class to write it all down. However, in the book Snape takes two points from Gryffindor; in the film he takes five.
