Sirius Black casting

[wimdiddlius_flumpugus]

Hi, I've been a member of this group for a while now but I came out 
of my cave today to comment on casting. The guy who plays Luka Kovach 
(not sure if that's spelled right) on ER is exactly who I imagined 
Sirius as. Sorry, but I don't know the actor's name, I'll check the 
next time I watch it. It's really too bad he's not British.. he would 
be great IMO.
