《断背山》是一部深受观众喜爱的电影，以下是一些经典对白：

Ennis Del Mar: [crying] Well, why don't you？ Why don't you just let me be？ It's because of you that I'm like this! I ain't got nothing… I ain't nowhere… Get the fuck off me! I can't stand being like this no more, Jack.

Jack Twist: [stop smiling] Tell you what... The truth is...... （breathing hurrily） Sometimes I miss you so much I can hardly stand it.

Ennis Del Mar: I wish I knew how to quit you.

Jack Twist: I wish I knew how to quit you.

Ennis Del Mar: You know what I miss about you？ I miss the way you smell.

Ennis Del Mar: I'm gonna tell you this one time, Jack fuckin' Twist, and I ain't foolin'. What I don't know - all them things I don't know - could get you killed if I ever find out. I mean it.

这些对白展现了角色之间深刻的情感纠葛和内心挣扎，是《断背山》这部电影中最具代表性的部分。
