The movie veteran has joined the cast of the U.K. series as U.S. socialite Martha Levinson and while she has enjoyed working with the likes of Dame Maggie Smith, Hugh Bonneville and Michelle Dockery, she was surprised at how unaffected they were by the wintry weather.
She tells People magazine, ""The best and the worst thing was the weather. I couldn't get over how much I loved it yet how difficult it made my life. It's nothing to the English actors. A windstorm could come in and blow off their wigs and they will just keep going.""
MacLaine, 78, stars as the mother of Elizabeth McGovern's character, Cora Crawley, Countess of Grantham in the current third season of the show and she's keen to reprise the part in future episodes, too.
She says, ""I have no idea what Julian (Fellowes, creator) is writing. I did suggest that he bring a few of them to America. I want to see the Downton group Stateside!""
