'The Big Country'
Near the end.
The Major says he'll go it alone.
Charlton Heston grimly pulls his hat on, mounts up, and rides after him
Cue great music as he rides up beside the Major.
Then round the corner follow the rest of the men.
Cue amazing musical score and hairs on back of neck (play full volume!!)
Absolutely fantastic scene.
Just watched it on Sky+
