Picture a futuristic, butt-kickin' warrior-princess, terrorizing the galaxy with her high-tech weapons of mass destruction.

Now picture Megan Follows in the role.

There is something inside the Canadian period-piece veteran that would love to go the sci-fi route, just to change it up.

"Yeah, a Terminator/Transformer woman," Follows said enthusiastically.

The thing is, going back to her days playing a young Anne of Green Gables, there is something about Follows that always has fit roles set in the past. Tonight, for example, Follows stars as a 1930s Toronto mom in Booky's Crush on CBC.

"I love all periods," Follows insisted. "I don't really care. I just love a good role."

To be fair, it's not as if Follows limits herself to period pieces.

As we spoke to her recently, she was just finishing up a guest-starring spot on the Tim Roth series Lie to Me, which airs on Fox and Global. And that came on the heels of Follows having filmed a guest-starring role on Brothers and Sisters, which stars Sally Field, Calista Flockhart and Rob Lowe, and airs on ABC and CTV.

"I'm not in flashback scenes or anything like that -- that would be Cold Case," Follows said of her appearances on U.S. network programs this season. "So there's lots of contemporary clothing there. Sometimes, when you're doing contemporary stuff, the most fun part is you get to wear fantastic clothes."

The clothing isn't quite so glamourous in Booky's Crush, which is the latest in a series of made-for-TV movies based on the Depression-era stories by Bernice Thurman Hunter.

Eleven-year-old Booky Thomson (Rachel Marcus) and her friends have entered a new grade at school and suddenly are noticing boys. Booky is infatuated with the lad she's tutoring and she gently is guided through her first crush by her parents Francie (Follows) and Thomas (Follows' real-life husband, Stuart Hughes).

"Maybe it's because of my parents and the fact I grew up watching a lot of theatre," Follows said when asked why the makers of period pieces tend to seek her out.

"This is not unlike the British discipline. A lot of British actors are good at period pieces and sometimes that just has to do with making the language sound comfortable coming out of your mouth, even if it's very different from who you are.

"It's just a skill, to be honest. I've done a lot of contemporary things as well. But even in the theatre now, you can have something that's considered a classic that was written in the 1980s. Shoulder pads and frosty blue eyeshadow, that's now part of the classical repertoire."

Well, if that's the case, then sci-fi must be the next logical step for Megan Follows. But be warned, Megan, some of those sexy, warrior-princess space-suits can be rather form-fitting.

"That's true, you can't be eating that extra doughnut, unless you happen to have that particular role on the spacecraft," Follows said. "There's usually one of them who has been eating too many space rations."
