Watch: Trailer for Alison Ellwood and Alex Gibney's Showtime Band Doc 'History of the Eagles'

"History of the Eagles," a two-part documentary about the Eagles directed by Alison Ellwood ("Magic Trip") and produced by Alex Gibney, heads to Showtime on February 15th and 16th at 8pm after the first part had its world premiere at Sundance in January.

The films piece together never-before-seen home movies, archival footage and new interviews with band members, as they reflect on their long and sometimes troubled history together. As one of them puts it, "It's just about a journey from innocence to experience."
