Just got back from a local comics/cards/toys fair where I handed out a few hundred Supanova flyers for the Sydney and Perth shows so I'm sure it's okay to mention the new guests here
You already know about Ray Park and Dirk Benedict et al but we now have Richard Hatch (original Battlestar Galactica, current Battlestar Galactica) joining the film and television guests!
And, for the comic fans, in addition to Dave (Watchmen) Gibbons, Nicola Scott and others, we now have in the roster, the highly talented artist Tim Sale! Tim's work has been seen on the Heroes television show as well as books such as Superman For All Seasons, Batman: Dark Victory, Batman: The Long Halloween, Hulk Gray etc.
I'm looking forward to meeting both new guests, especially Tim Sale who with Dave Gibbons are artists whose work I've enjoyed for some years. Best,
Royd
