Amber Marshall is a star on the Canadian TV landscape.

She plays the leading character, Amy Fleming, in CBC's No. 1 drama Heartland, which wraps up tomorrow night in the second season finale.

But the Londoner doesn't seek the limelight in any way and she's not addicted to fame or her popularity that had more than 500 people wait in line to get her autograph at a promotional event in Vaughan recently. In fact, Marshall doesn't even know if she'll stay in acting.

At 20, her whole life is before her and she's not rushing into anything.

"I still don't know if this is going to be my career. I'm very open to anything," she said from her North London home this week, where drawings from young fans are on her fridge and a poster of the Heartland cast sits just above it.

Relaxed in blue jeans and a green sweater, Marshall is excited that she'll start filming Heartland's third season in Calgary in May.

"No one really had any expectations for it. As we were going into Season 2 there was talk of a Season 3 and we said, 'Do you think that's possible?'"

She wouldn't give too many hints about tomorrow's finale or Season 3.

"It's a very exciting episode. It will join in with next season. We tried to wrap everything up as nicely as possible . . . but there are some good little cliffhangers."

Marshall said she feels more comfortable in the role of Amy with each passing season.

"The writers have paralleled my character with myself. It's kind of nice when I get the scripts and I say, 'That's very much me.'"

Marshall said it's a dream job because she gets to ride horses every day. She's been a horse lover since she was a youngster and she has horses at a farm northwest of the city.

The former Original Kids theatre company member, likes all animals and has two dogs -- one from an animal rescue organization that is still afraid of people -- two cats and a chameleon.

She picks up the chameleon to show how it changes colour when it gets mad. It needed medicine this past year and since she had to force the creature to take it, the chameleon now doesn't want to be touched, she explained.

Marshall mainly hangs around home these days with her parents and heads out of town to ride once a week.

Interestingly, Marshall's father played hockey against a Heartland cast member, Chris Potter, when they were growing up in London.

Marshall is pleased to have Potter in Calgary filming with her.

"It's nice to have that tie to London for me. He's that father figure while I'm there and we've bonded quite well."

Marshall is recognized more and more in public and she finds it funny that in her hometown most people don't approach her because they don't think a Heartland star would be in London.

"When I'm in London, they think, 'There's no way she'd be here.'"
