Unlike many other documentaries that premiered at the 2011 Tribeca Film Festival, 'Talihina Sky' -- the film chronicling the rise of Kings of Leon -- is a work in progress. While the film has been 10 years in the making, drummer Nathan Followill believes it could become a series as opposed to a typical two-hour movie.

"We're still filming," Followill tells Spinner. "It's going to be like 'Lord of the Rings,' but it'll be 'Lord of the Kings.' It's going to be a trilogy for sure."

Even though they weren't there to see the band play, throngs of enthusiastic Kings of Leon fans filled the Tribeca Performing Arts Center, which made Followill feel like he was supposed to be performing at the festival instead of watching a movie. "We had no idea it was going to be anything like this," he says. "It's like a show rather than a movie premiere, but I'm pretty stoked."
