...Rhinestone (1984)

The saving grace in Rhinestone are the clips, here and there, in which you see and hear Dolly Parton singing and strumming her guitar. The script, designed to mirror the hit song Rhinestone Cowboy (which is not even used in the movie), is just a sea of caricatures with Sylvester Stallone screeching Medusa-like in any number of shitatious scenes. The movie is strictly for Dolly Parton completists (especially those who want to see La Parton kiss a man) or terrorist torture.

For the Love of Dolly (2006)

For the Love of Dolly, more than being a love song to the titular singer, is a love song to the five fans who have devoted their lives and homes to her. Although Dolly Parton appears in the documentary it is through the use of digital video filmed by fans and not interviews; in fact, only one Parton-performed track is used in the movie at all (Hello God over the final credits). The fan profiles are both poignant and uplifting - two adjectives I would also use to describe the beloved singer/songwriter herself.
