Smallville seems to be getting more and more guest stars these days. We've heard about members of the Justice Society stopping by along with the Wonder Twins upcoming visit.
MTV has mentioned that executive producer Brian Peterson has revealed that both Zatanna and Martian Manhunter will return at some point in this season. If my memory serves me, I seem to recall that people were pleased with Zatanna's appearance.
There hasn't been any confirmation whether or not the same actors, Serinda Swan and Phil Morris, will return to the roles. You would think it'd be crazy if they did recast them if there were any questions of salary or availability. The good thing about the show is that they haven't tried to recast Michael Rosenbaum as Lex or Sam Jones III as Pete Ross (although I'm sure there would be viewers that wouldn't mind if Lana Lang was recast).
Peterson also said that they were hopeful for another season after this. He feels there is still more stories to tell about Clark before he fully becomes Superman. I'm not sure if I agree with that.
Are you excited about the return of Zatanna and Martian Manhunter? Would you want to see a tenth season after this? Does it bother you that Clark still hasn't become Superman?
