Instructions for actors usually are simple: Look good and don't think.

But the two stars of Bones -- Emily Deschanel and David Boreanaz -- have added producing titles for the show in recent seasons. Deschanel was asked if that has been a good thing, or if it merely means she worries more now about the business side of the equation.

"Sometimes people want to keep actors in the dark -- you know, 'Don't tell them that, just let them be pretty' or whatever," Deschanel said. "That can be frustrating.

"I mean, I'm really good at being pretty, but come on!"

Bones returns for its fifth season tonight on Global in Canada, and then tomorrow on Fox, which is the show's network of origin. Deschanel said she's still enjoying playing Dr. Temperance (Bones) Brennan, an uber-nerd with no social skills and a merely sporadic knowledge of pop culture.

"Brennan has no idea who Britney Spears is, which I love because it's like Brennan filled her brain with entirely useful information that she uses in her day-to-day life, so why would she fill it with anything frivolous like Britney Spears?" Deschanel said.

"But I also love that characters have contradictions. Brennan did know who Stewie from Family Guy was."

Family Guy, of course, is another Fox show. What a coincidence!
