Billy Bob Thornton: 'Willie Nelson's a legend'

Billy Bob Thornton has called Willie Nelson "a legend".

Thornton premiered his new documentary about Nelson, called The King of Luck, last week at the South by Southwest festival in Austin, Texas.

The actor-director called the film a tribute to the country music star, reports The AP.

"We just wanted to do an accurate and loving tribute to Willie," Thornton said.

He added: "He's a guy that's been a legend, especially in these parts, for a long time and we thought he deserved kind of a full-length documentary."

The Oscar winner described the documentary as "a movie that's told by the people around him, who love him and we thought he deserved it".

The Eagle Eye star also revealed at the festival that he was in discussions to star in a sequel to his 2003 comedy Bad Santa.
