In guide, Harry, Hermione and also Ron visit St Mungo’s to see Arthur Weasley after the serpent strike, in the process facing their old DADA teacher from book 2, Gilderoy Lockhart, that is a title patient there after the backfired Memory Charm. The reality Arthur was at St Mungo’s whatsoever is glossed over in the film. Harry’s investing the Xmas vacations at Grimmauld Area is cut; Snape fulfills him there to tell him about his upcoming Occlumency lessons. In the film, St Mungo’s is avoided totally, therefore the Occlumency lessons commence promptly once it’s clear Harry is seeing right into Voldemort’s mind.
Harry has a lot extra lessons with Snape than are revealed, and also is rejected of title them because he deliberately looked at Snape’s memories in the Pensieve, not since he saw them by mishap utilizing the Shield Beauty to rebound the Legilimens Charm (though that does occur). The OWL testing is hinted at in the movies, but there’s much more in guides; all the useful spellcasting including another Patronus shot right at Umbridge, Harry collapsing and also seeing Sirius hurt during his Background of Magic test, seeing Hagrid assaulted throughout Astronomy; all omitted.
