Cabler will show 'The Promise' in October

HBO will air the Bruce Springsteen docu “The Promise: The Making of Darkness on the Edge of Town” in October.

From director Thom Zimny, who has worked with Springsteen on several projects, film captures the tumultuous time Springsteen had between “Born to Run” and “Darkness,” his fourth album.

For much of that 1975-78 time period, Springsteen was entangled in a lawsuit with his former manager Mike Appel that prevented him from recording any songs. Doc will offer never-before-seen footage, including home rehearsals.

“The Promise” will also unspool at the Toronto Film Festival, to be held in September.
