Question: Now that we know that Smallville's coming back next season,
when will we find out which cast members will be returning? — Kirsten
Ausiello: You'll find out right this second (Warning: This spoiler
will dramatically and suddenly accelerate, climb, stop and dive. It is
not recommended for Smallville fans who are expectant mothers or those
with a history of neck or back conditions or heart trouble) OK, here
we go: Nearly everyone is expected to return for Season 8 except —
wait for it, wait for it — Michael Rosenbaum and Kristen Kreuk. I'll
give you a second to catch your breath. [Beat] Sources close to the
show tell me that both actors have informed producers that they don't
intend to return as series regulars next season. However, they are
open to doing limited engagements, and those details are being worked
out as we speak. Thanks for riding! Actually, you may wanna stay
strapped in for this next one...
