Sundance Channel will offer more documentaries via iTunes starting today.

In a story from Variety, the channel will be making The Hill (a reality type show that focuses on the office of Democratic Congressman Robert Wexler), The First Amendment Project (a doc that looks at free speech in America), and The Staircase (another doc about the "mystery surrounding the death of Kathleen Peterson, who was married to novelist Michael Peterson") available.

Sundance Channel will also be offering the documentary One Punk Under God, about punk preacher Jay Bakker, as a free download from December 5 to December 12.
