Johnny Depp has announced his plans to buy the Wounded Knee historical landmark and give it back to the Native Americans.
He is ready to spend close to $4 million on the site, where many Native Americans were killed in the 1890 massacre.
"It's very sacred ground and many atrocities were committed against the Sioux there," he said.
"And in the 1970s there was a stand-off between the Feds and the people who should own that land. This historical land is so important to the Sioux culture and all I want to do is buy it and give it back. Why doesn't the government do that?"
Having always been interested in Native American culture, his passion for it was highlighted when he played Tonto, an Indian in movie the Lone Ranger.
He said he got the permission of various tribes before he played the role.
"The main thing was, 'Are we doing right by the Indian? Let's not make any mistakes here,'" he said. "The idea was to give back to them and to make sure that we got it right."
"The production was blessed by the Navajo and the Comanche and I got a call from LaDonna Harris, who has been a Comanche activist for many years, to say that she wanted to adopt me into her family and into the Comanche nation. It's a great honor," he said.
Though Lone Ranger failed at the box office, Depp is ready to spend a big chunk of money to save the land.
The asking price for the land is $3.9 million.
"I am doing my best to make that happen. It's land they were pushed onto and then they were massacred there. It really saddens me," he said.
The site is located on the Lakota Pine Ridge Indian Reservation in South Dakota. The massacre took place during the last major battle of the American Indian Wars. American troops tried to disarm the Lakota Indians. Because one elderly tribesman refused to hand over his weapon, the attack began.
It is not known how many people died, but the estimate is that 150 people, including men, women and children, died. The massacre angered many, especially because at least 20 American soldiers were awarded the Medal of Honor for their role in it.
