As Potter has his final battle with Lord Voldemort on the big screen, audiences will say farewell to the world of Hogwarts after 14 magical years since the first book captured the imagination of millions of readers in 1997.
Harry Potter and the Deathly Hallows: Part 2 has been highly anticipated by fans; the seven previous films - all among the 30 most successful films of all time - jointly grossed US$6.3 billion.
Avid fan Harry Tsang Wai-lung, 22, is excited about the new film, but also reluctant to say goodbye to the magician with whom he grew up.
He said the Harry Potter stories were more than mere fiction, for they had taught him life lessons.
"When there is a wand, there is a way," he says. "It teaches me that whenever I am in doubt of my ability, I should believe in who I am." He has read all the novels twice and seen the movies many times.
Another fan, Jayson Paolo Albano, 16, is desperate to see the film. When he first heard the seventh film would be split into two parts, he thought it would ruin the story. But now he realises that it gives the filmmakers time to go into greater detail like the book.
"Yet after the movie comes out, what am I going to look forward to? Twilight? I don't think so ... Harry Potter has been an important part of my childhood, so, if anything, it's good to say a proper 'Goodbye' to it by watching the last movie," he says.
