Actress Daryl Hannah was arrested Tuesday along with more than 100 others who refused to move while participating in a sit-in protest near the White House against an oil pipeline project.

The 50-year old actress was seen smiling when the police got her handcuffed, after the protesters declined to move from the sidewalk near the White House where they were sitting.

Sometimes it's necessary to sacrifice your freedom for a greater freedom, Hannah told WRC-TV before the arrest. And we want to be free from the horrible death and destruction that fossil fuels cause, and have a clean energy future.

The Kill Bill star joined environmental activists on Tuesday to protest the Keystone Pipeline System, which will transport synthetic crude oil from the Athabasca Oil Sands in northeastern Alberta, Canada, to refineries in Illinois and Oklahoma, and on to the U.S. Gulf Coast.

The system consists of the already operating Keystone Pipeline and proposed Keystone XL (Keystone Expansion) pipeline. Keystone XL has faced lawsuits from oil refineries and criticism from environmentalists and some members of the U.S. Congress. The U.S. Department of State in 2010 extended the deadline for federal agencies to decide if the pipeline is in the national interest.

Hannah has been released from custody after paying a $100 fine, latest reports said.
