PARK CITY, Utah (AP) — When people see the new Showtime documentary "The History of the Eagles," what may surprise them most is how much fun the band had together.

The quartet appeared at Sundance on Saturday before the preview of the film, which will air in two parts on the network Feb. 15 and 16.

Henley says the media likes to focus on their well-documented tension, but he insists that's overblown.

The film was produced by Academy Award-winning filmmaker Alex Gibney.

Glen Frey says the band hopes to make new music at some point as well.
