Sam Witwer and Cassidy Freeman will be double trouble for Clark Kent

Even though "Smallville" is entering its eighth season, there's no shortage of bad guys.

The CW has cast Sam Witwer and Cassidy Freeman as the two new villains that will give Clark Kent grief on "Smallville" this fall, according to The Hollywood Reporter.

"We're thrilled that Sam and Cassidy will be joining the cast, and we have some very exciting things in store for them, their characters and 'Smallville' fans for this season," executive producers Kelly Souders, Brian Peterson, Todd Slavkin and Darren Swimmer said in a statement. "They are both incredibly talented performers, and we cannot wait to begin to work with them."

Witwer, 30, will play Doomsday, born Davis Bloome, who is an easygoing, self-effacing paramedic who learns about a shadowy evil in his heritage. Witwer is best known for playing Alex "Crashdown" Quartararo on Sci Fi's "Battlestar Galactica."

Freeman will play Tess Mercer, the acting CEO of LuthorCorp who was handpicked by Lex to succeed him before he vanished into the ether last season. Freeman was in "Finishing the Game: The Search for a New Bruce Lee" and was coincidentally cast as the tough, attractive paramedic Charlie in the CW's medical pilot "Austin Golden Hour."
