The original 70s movie poster
It's about an aging country singer songwriter named Maury Dann who is on the road, working his way through gigs, women, alcohol and more during the day and a half of time the viewer spends with him.
It's a fully certifiable "Man Movie"-- that is, women are objects, hysterical and insecure, while the men grapple with their own manliness and keeping up appearances of masculinity. There's a lot of beer and belt buckles in this movie, is what I'm saying. There's gambling, hunting and fist fights and even a stabbing and a car accident! So much action, so much manliness on the line.
The movie is interesting because Maury is so completely flawed and dynamic. He is more than slightly off the rails and no one has ever really been able to rein him in. We see him using and abusing overeager women and handing his mother a pile of pills to keep her quiet, yet we also see him gently pressing his face against his beloved spaniel when he realizes he can no longer keep him. It is clear that he thinks of himself as a great singer songwriter, but the film shows that the gigs are no longer as big as they used to be and that he has not had a radio hit in a while, if ever. Maury's life seems to have moved for years, decades maybe, at a non-stop pace-- from gig to car to hotel to radio station to restaurant and on and on and from whiskey to women to pills to weed and on and on and on. While he is busy puffing himself up, he actually appears more and more degraded.
