i think he failed to get a speaking part but is in the leaky cauldren (i think reading a simon scharma book - but i may be lying there!) still haven't seen it but will keep an eye out...
I was a bit irritated by it. It was a bit distracting suddenly thinking "ooh, it's him!", especially as he wasn't a character. He was right in the foreground as well (as far as I remember). They could have at least had him on a table near the back.
