I think Gary Oldman was a wonderful actor and portayed the personality of our "un-hinged" Sirius very well.

However, I did feel that they could've done a better job of having him portray him physically. His hair was brown, not black. This annoyed me. And, honestly, do you see Oldman as being the hearthrob that Sirius was? I don't, but that is my opinion.

I'm waiting anxiously to see who is cast for young Sirius!!! He'd better be hot...
