Sam Witwer, first known to Star Wars fans for his role as the Secret Apprentice in The Force Unleashed and its sequel, recently joined The Clone Wars cast as the scheming, malevolent Son. In an interview posted yesterday, Witwer spoke to IGN's Eric Goldman about his new role as the Dark Side personified.

Here's an excerpt from their conversation:

Because I was with Dave Filoni on that first day and we were doing some of the lines and I said, "Listen, are you concerned that I'm going to sound a little bit too much like Starkiller in this?" And he goes, "Well, actually, that's kind of why I hired you. If your character is the Dark Side of the Force, then you might hear a little bit of Starkiller's voice in him." And when Dave said that to me, I said, "Well, then you should hear everyone in my voice. You should hear all of the different characters in my voice. You should hear Darth Vader at times. You should hear the Emperor at times. You should hear Starkiller. Darth Maul. You should hear elements of all these different Star Wars dark side characters, because in a sense, this character is all of those characters.
