Victoria Principal, who's been planning to break out of her "serious actress" mold for years, is still appearing in dramatic television movies.

And she's got no one to blame but herself. She's not only acting in her latest project, "Don't Touch My Daughter" (Sunday, 8 p.m., Ch. 2), but it's produced by her company."I keep talking about doing comedy, but it never seems to happen," Principal said with a laugh during a telephone interview. "I can only figure that as much as I love to laugh, I'm drawn to the dark side of performing."

In "Daughter," Principal portrays the mother of an 11-year-old girl who's kidnapped and sexually assaulted by the father of a classmate. What's almost worse is the inability of the legal system to prove the case or protect the victim.

"It's really about every mother's worst nightmare come true," Principal said.

The movie begins as fairly standard television fare. But midway through, there's a big twist in the plot, redeeming the project considerably. And there are a couple of other surprises that make it a bit better than the average TV fare.

"This is one of those movies that just when you think you know where it's going, it turns several times," Principal said.

And, as executive producer, Principal had a hand in all facets of the project. While she isn't as visible as she was during her nine-year stint on "Dallas," she's very busy. Her production company has more than a dozen projects in various stages right now, including a new series for her on ABC.

"I love the business side of this industry," she said with gusto. "I love making the deal.

As a matter of fact, at one point in her career she gave up acting to become an agent. She also attended law school just to help her in her business dealings.

As much as Principal enjoys talking about her work - she's one of the few actresses who genuinely seems to like doing interviews - she is even more enthusiastic when it comes to talking about her husband, surgeon Harry Glassman.

"My husband is the most extraordinary man and remains my hero," she said. "I love going through my life with him."

Principal, who once was a regular on the covers of the supermarket tabloids with stories about her romances, has put those days behind her. She's about to celebrate her sixth wedding anniversary. And even she's a little bit surprised by that.

"I had never anticipated that I would be a happily married woman," Principal said candidly. "I'd never even thought I'd be a married woman - because of my flamboyant past and because I didn't have a very good track record in terms of longevity.

"But I think the marriage speaks for itself."
