For instance, Dobby the house elf was only on screen in Chamber of Secrets and right before his death in The Deathly Hollows Part 1.
Conversely, Dobby was present in every novel since his introduction, making the character death devastating for fans of the novels.
Peeves being cut from Sorcerer’s Stone is just one of many examples that adapting the long and detailed Harry Potter novels for film is no easy feat.
His death in the movies had no emotional impact for moviegoers or casual audiences they could have easily forgotten about Dobby in the many years between his appearances.
