There where a lot of good scenes but one particular scene that I really liked was when Johnny Cash was first time auditioning for the record producer Sam Philips. Johnny and his band sang a generic gospel cover song. Sam Philips made them stop, and said he did not like it. Johnny asked him to elaborate,
Sam Phillips: You know exactly what I'm telling you. We've already heard that song a hundred times. Just like that. Just... like... how... you... sing it.
Johnny Cash: Well you didn't let us bring it home.
Sam Phillips: Bring... bring it home? All right, let's bring it home. If you was hit by a truck and you were lying out there in that gutter dying, and you had time to sing one song. Huh? One song that people would remember before you're dirt. One song that would let God know how you felt about your time here on Earth. One song that would sum you up. You're telling me that's the song you sing. That same Jimmy Davis tune we hear on the radio, all day. About your peace within, and how it's real, and how you're gonna shout it? Or... would you sing something different. Something real. Something you felt. Cause I'm telling you right now, that's the kind of song people want to hear. That's the kind of song that truly saves people. It ain't got nothin to do with believin' in God, Mr. Cash. It has to do with believin' in yourself.
Johnny Cash: I got a couple of songs I wrote in the Air Force. You got anything against the Air Force?
Sam Phillips: No.
Johnny Cash: I do.
Then the true Johny Cash sang from the heart his own song.
Go see the movie, I won't ruin it any further.
