I've actually always favoured Martin Short to play Remus. Despite his head and body being freakishly out of preportion (or at least in my opinion, with some make up (eye bags, and just general oldness lines) he could make a dencent Remus. I had a guy lined up for James, and I wrote it own, and he looked like SUCH an older Harry. I know he was in Sublet, which was a really weird movie about a guy livng in this other guys house, but then he finds out the other guy is actually himself. anyhoodles...
I agree with you on the guy for Sirius. He was so totally cute! I can rememebr having a crush on him when the Tenth Kingdom (the tv show) came out. In all fairness, it wasn't that long ago ::embarressed grin::...
