Watch out for ... Ellen Page

From its very first screenings, "Juno's" breezy blend of blog-age humor and old-fashioned emotion has garnered audience reactions verging on the ecstatic.

The film -- marking the debut of screenwriter Diablo Cody and a follow-up to "Thank You for Smoking" from director Jason Reitman -- tells the story of a pregnant 16-year-old with easygoing sass and a big heart. Much of the film's power comes from the performance in the title role of 20-year-old Canadian actress Ellen Page.

Although she was already something of a show-biz veteran, Page first came to the attention of broader audiences with her role in David Slade's 2005 revenge drama "Hard Candy," which led to a role in "X-Men 3: The Last Stand."

With her uncanny combination of world-weary cynicism and wide-open wistfulness, an unlikely mix of snark and innocence, Page's teenaged and pregnant Juno feels like a near-definitive portrait of contemporary youth in transition, as adolescent abandon gives way to a nascent maturity.

Page recently called in from her home in Halifax, Nova Scotia. The siren song of such media towns as Toronto, New York or Los Angeles might seem like a natural next step, but for now, she says, she's staying put.

"As things progress, it actually gets easier for me to be here. It kind of allows me the distance," she remarked. With the unexpected awards buzz building for "Juno," she'll probably soon seem closer than ever.

Here, she opens up about a lack of authentic portrayals of girls in the media and turning from darker fare to something a little lighter.

So far audiences are having a really explosive response to "Juno." Why do you think people are reacting so strongly?

I think it's unique. I think it's extremely genuine and honest and devoid of any stereotype.

And it is, compared to other work I've done, a quote-unquote lighter film. Yet to me, I remember when I read it for the first time, it was just like a breath of fresh air.

It was so nice to read something that felt so sincere. And a character had been written for 16-year-old girls that was showing a lot more interesting aspects than what we're used to in popular media right now. That was very exciting.

I don't want to ask "Did you see yourself in the character of Juno," but did you feel the script portrayed a teenage experience that was perhaps more recognizable to you, not one of makeup and slumber parties and a "Princess Diaries"-style fantasy?

Yeah. And no judgment towards that -- that could be a lot of individuals' idea of their teenage years.

But I suppose it occurs so much, constantly, that we forget there's other aspects. So sometimes when there's a character like that, or even Haley in "Hard Candy," there's this, 'Oh, it's so unrealistic. That's not a teenage girl.' And that becomes so frustrating.

I was like Juno when I was younger in certain ways, as were my friends. Sixteen-year-old girls do wear sweater vests and flannel shirts, and that's OK.
