|"Neither can live while the other survives..."
It has been suggested that this article or section should be merged with Harry Potter and the Prisoner of Azkaban (video game).
A novelty for the Harry Potter game series is the fact that Ron and Hermione are playable as well. You cannot play one character through the whole game. Instead, you automatically get switched at different parts to another character.
- Harry Potter (voice: Tom Attenborough and Harry Robinson): Harry is the only game character who can jump across chasms, he's the fastest runner and he alone has access to the Marauder's Map. Harry has Glacius and Expecto Patronum as exclusive spells. Harry is one of the two playable characters that can ride Hippogriffs, the other being Hermione. Completing the Famous Wizard Card sets Wizards and Quidditch will boost Harry's health permanently.
- Ron Weasley (voice: Greg Chillin): Ron is the sneaker of the gang - he can open secret passages and search bookshelves for items, as well as using Stink Bombs and Stink Pellets, but he has the smallest spell arsenal. His only exclusive spell is Carpe Retractum. Ron is the only playable character that cannot ride a Hippogriff. Completing the Famous Wizard Card sets Dragons and Classical Beasts will boost Ron's health permanently.
- Hermione Granger (voice: Harper Marshall): Hermione is the last character to join. She has the highest base power of her spells and has the greatest spell arsenal, as well as the ability to crawl into tight spaces, but she is the slowest runner. She has Draconifors and Lapifors as exclusive spells. Hermione is also one of two playable characters that can ride Hippogriffs, the other is being Harry. Completing the Famous Wizard Card sets Witches and Hags will boost Hermione's health permanently.
- Buckbeak: Buckbeak is Hagrid's pet Hippogriff. Only playable when Harry or Hermione is flying him.
The game includes a Trailer from the Film, Wizard duels, a Gallery and more. The Bean Bonus Room is also available for collecting more sweets.

Behind the scenes
- The game begins with Harry, Ron and Hermione on the Hogwarts Express, entirely omitting Aunt Marge blowing up, the Knight Bus, and the Leaky Cauldron.
- Harry's appeance in the game is vastly different than that in the film. He has longer hair like he did in the previous book and speaks differently too (a lot more slower).
