Check out some Sirius-ly great memes for Gary Oldman's birthday!

Indeed the Sirius Black actor turns 55 today, and in honor of his birthday we've collected some memes that celebrate all the charm, charisma and especially seriousness he brought to that role in the Potter film series.

Fans may also of course remember that time Sirius had to bring the Joker to justice when Batman couldn't step up to the plate. Then there's the matter of Sirius Black's daughter, who changed the world with that awful video - (though I do plan to watch it tomorrow).

There was yet another time Sirius dissed Voldemort so badly that the Dark Lord had to do this, and then the legend of Black spread throughout the land, the Wizarding World, (and even somehow Middle-Earth!).

Happy Birthday good sir!
