The backstory of the Eagles is one of rock’s greatest soap operas. Band member in-fighting, back-stabbing, feuds: it’s all there. Soon, we’ll be able to watch the drama of the band unfold as it happened on the big screen: filmmaker Allison Ellwood will be premiering the first of her two part documentary, The History Of The Eagles at the Sundance Film Festival in Utah.

The film was split into two parts covering two eras of the group: the first follows their rise to success and eventual breakup in the 1970s, while the second half covers the members’ solo careers and their eventual reunion. The four current members of the Eagles (Don Henley, Glenn Frey, Joe Walsh, Timothy B. Schmidt) were participants in the film, and Ellwood interviewed past members Randy Meisner, Bernie Leadon and Don Felder, as well. Former songwriting partner Jackson Browne also made an interview appearance.

While the film will cover some of the infighting between the band members, Ellwood told Billboard that she did not set out to vilify anyone in the band. “Nobody comes off as a villain,” she said, “The problems that occurred – all the band members talk about it. It was just this thing that imploded on itself.”

Part 1 of the doc premieres January 19th at the Eccles Theater in Park City, Utah; it will then be screened in Ogden and Salt Lake City as part of the Sundance festivities. The Eagles are expected to attend the premiere in Park City.
