Margot Kidder and Christopher Reeve in 1978’s Superman.

CALGARY - Superman wasn't there to save Lois Lane when she ran into trouble outside the White House Tuesday morning.

Canadian actress Margot Kidder, who played the love interest in four of the five Superman films, was arrested in Washington, D.C. along with others protesting America's support of the Calgary-based TransCanada Corp.'s Keystone XL pipeline project.

The $7 billion project is planned to move oil from Alberta to the Gulf Coast and protestors are hoping to convince President Barack Obama to scuttle the plan.

The Washington Post reported the 62-year-old actress joined 20-30 others for a sit-in when U.S. park police arrived to break it up and toss the lot of them into the back of a paddy wagon.

Reports say Kidder's friend and fellow Canadian actress, North of 60's Tantoo Cardinal, was also among those arrested.

Dozens of protestors have been arrested since the two-week act of civil disobedience began outside the White House.

Kidder is the first of a handful of Hollywood heavyweights who've vowed to join in the demonstrations, with Shutter Island's Mark Ruffalo and Lethal Weapon star Danny Glover also planning to attend.
