Natural horseman Buck Brannaman will appear on “Late Show With David Letterman” tonight, June 23, at 11:30 p.m. EST on CBS.
Brannaman starred in the documentary Buck, which tells the tale of his transition from an abusive childhood to developing a tremendously successful approach to horses. That film, which has been accepted to the 2011 Sundance Film Festival, started playing in select theatres on June 17.
