People.com Entertainment TV Let Frank Sinatra Seduce You All Over Again in the 'Sinatra: All or Nothing at All' Trailer The four-hour docuseries airs over the course of two nights in April on HBO By Tara Fowler Published on March 6, 2015 01:55 PM Share Tweet Pin Email Photo: William Gottlieb/Redferns A new documentary offers an intimate look at the life and career of Frank Sinatra, complete with family interviews and never-before-seen footage. Sinatra: All or Nothing at All is a four-hour docuseries that will air over the course of two nights on HBO – and PEOPLE has the exclusive trailer, which you can check out above. The series focuses on the first 60 years of Sinatra’s life and is largely told in his own words with commentary from those who knew him best. Director Alex Gibney used the set list from the singer’s 1971 “Retirement Concert” in Los Angeles as a guide for the film’s narrative. “It’s like his autobiography, but it’s told through song,” Gibney said during the Television Critics Association’s semi-annual press tour back in January. “To hear him narrate his own life through these interviews is what it made it worth doing.” The project is Gibney’s second with HBO this year. He also directed the controversial documentary Going Clear: Scientology and the Prison of Belief, which premieres March 29 on HBO. Catch Sinatra: All or Nothing at All on April 5 and 6 at 8 p.m. on HBO.
