'Dances With Wolves' Mary McDonnell Splits With Husband After 37 Years

'Dances With Wolves'star Mary McDonnell has split with her husband, Randle Mell, after 37 years of marriage.

According to legal documents, obtained by The Blast, McDonnell filed for legal separation from her longtime husband in Los Angeles County Courts. The legendary actress is well-known for her portrayal of 'Stands with a Fist' in the breakthrough performance in the movie starring Kevin Costner. The actress was nominated for an Academy Award for best-supporting actress in the film.

McDonnell scored another Oscar nomination for her leading role in the movie 'Passion Fish.'

In 1984, Mary married actor and co-star Randle Mell, who starred in the movie 'Grand Canyon' with McDonnell. It should be noted, Mary has filed for "legal separation" and not the full-blown dissolution of marriage. So, it's unclear why the actress chose to go this route. Normally, in a celebrity divorce, a legal separation is filed to establish separate finances in the relationship. In a marriage of over 30 years, everything would be considered community property -- to be split down the middle -- except anything earned after the date of separation.

The actress opened up about her lengthy marriage in 2015, admitting it wasn't always a perfect situation. "In our case, we're both very stubborn. That doesn't mean we don't fight a lot, it's an Achilles heel kind of thing. There are power struggles that happen in my marriage that are just ridiculous because we're both very stubborn. But, in the long haul, that stubbornness has helped us get through the tough times. And I think we found each other through like-minded values," she told The Press Of Atlantic City. 

She continued, "I dated a lot of actors before my husband, but I didn't date very many actors who came from a big family, who wanted a family, who loved sports. . . he was like, 'Check, check, check.' And he was incredibly talented. I never develop a crush on an actor unless they're talented. Randy was so talented, and we have the same values still. I think that's extremely important in a marriage. I think there has to be a friendship."

The former couple shares two adult children, Olivia and Michael.

Interestingly, the ex-couple recently listed their Pacific Palisades home for $3.4 million. The sale of the family home might have been an indicator of the upcoming issues in the marriage. The famous duo purchased the home five years ago for $2.8 million. The single-story house has four bedrooms and 3.5 bathrooms in over 2,6000 square feet of living space.

At this point, it's unclear what prompted the legal filing.
