What is Sirius's last name in Harry Potter?

Answer 1

The actor who played Sirius was Gary Oldman.

Sirius in the books, was Harry's godfather. Comming from a long line of Slytherins, Sirius was actually put into Gryffindor. He quickly made friends with James Potter, Peter Pettegrew, Remus Lupin and various other people. It was at Hogwarts where Sirius learned how to transform into a black dog to keep Lupin company when he changed into a Werewolf. Sirius was never officially recognised in the wizarding world as an Animagus. When Hogwarts ended for the friends, Sirius Black became Harry Potter's Godfather. After Peter Pettegrew gave the Potters away to Lord Voldemort, Sirius went after him and tried to kill him. His attempts to do so landed Sirius in Azkaban Prison. Sirius escaped in the third book by transforming into the black dog. He went to find Harry, and in that book, the two form a closer bond. It is in later books where we see more to Sirius. We find that he has a home in Grimuald Place and has a pure-blood background. The Black family is very important to the plot of the series. Harry learns many things from his Godfather, and it is perhaps his death in the 5th book that spurrs Harry into action against Voldemort.
