Lukas Haas

"All those equations add up to something, I'm guessing," Lukas Haas says of the chicken scratch behind him. "Just don't ask me what it all means."

Haas joins the cast of Touch (returning Oct. 26 at 8/7c on Fox) this season as Calvin Norburg, an algorithm specialist at vaguely sinister Aster Corps, the research facility trying to hunt down Martin Bohm (Kiefer Sutherland) and his brainy son, Jake (David Mazouz). Norburg may be something of a reluctant evil genius, however. "He joined Aster Corps strictly for the money, but what he really wants to do is change the world. Watch for him to break away and go through a lot of unexpected changes."

Haas, best known as the kid who saw too much opposite Harrison Ford in Witness, marks his debut as a TV-series regular in the role. "On television you end up shooting five times as much material in the same amount of hours [as a movie]," he says. "That's an equation I may never understand."
