Although he's been playing the bad side of Brady lately, Eric Martsolf will soon be moving in a very different direction. The multi-talented actor has been cast as Booster Gold, a superhero from the future. The character won't be appearing in Salem of course. Instead, fans will be able to catch Eric on the CW/Sci-Fi channel series "Smallville."
No word yet on when the episode will be airing, but it looks like shooting will start right away. Martsolf has been forced to drop out of his appearance in next week's Soap Cruise: The Fourth Voyage because of the scheduling conflict.
Personally, I think he's got the build. Not sure about his acting skills.
