The movie is narrated by actor Liam Neeson, a former boxer, with the musical score by composer Lorne Balfe, whose credits include Inception, The Dark Knight, Iron Man and Sherlock Holmes.

Moore, 33, co-directed the film with Leon Gast, who won an Oscar for the documentary When We Were Kings, which detailed "The Rumble In The Jungle," the 1974 heavyweight championship in which Muhammad Ali  regained the title from George Foreman.

"Right now, we have a world premier scheduled at the The SXSW Film Festival in Austin, Texas in early March that will be announced formally sometime this week," said Moore.

"It's arguably the largest film/music/interactive festival in North America, and they're expecting over 300,000 attendees this year for that festival. We'll be one of the headlining events there.".

Moore said that he interviewed Mark Wahlberg, Jeremy Piven and Jimmy Kimmel, as well as boxing commentator, Larry Merchant, and other boxing journalists for the film.

Pacquiao's is preparing for a rematch with WBO welterweight titleholder Timothy Bradley on April 12 at the MGM Grand in Las Vegas.

Pacquiao lost to Bradley by split-decision in June of 2012 before being stopped in the sixth-round by Juan Manuel Marquez in December of that same year. Pacquiao is coming off a unanimous decision over Brandon Rios last November.
