[Corgi]

(I hope the interview reference isn't redundant -- I've been in
Manchester and therefore AFK this past weekend)

The idea of Jason Carter playing Sirius has even spread to Slovakia!

And then, in CBBC Newsround, one of the CoS producers SPECIFICALLY
says the actors playing Remus and Sirius should be a little older, to
match up Rickman.

[musically] Jason's forty-twoooo-oooo! [/musically]  (I'd hate to
think they'd cast 50-something actors after they slathered so much
youthful makeup on the Alan.)
