2. Sirius Black
Poor, poor Sirius Black. This guy has got one tough life. First he is wrongly accused for the murder of his best friends, spends a long period of time in Azkaban prison, only to finally escape and be murdered two years later by Bellatrix Lestrange. Even though Sirius’ presence is somewhat short in the Potter universe, it is without a doubt memorable. Sirius manages to go from being a terrifying and mysterious character to one of the sweetest and tragic wizards in the whole saga. Gary Oldman is almost unrecognizable in this performance.
Sirius’ Best Film: Harry Potter and the Prisoner of Azkaban.
