Only now does it occur to me... that before she appeared in the unintentionally comic period Western THE QUICK AND THE DEAD, Sharon Stone was in an intentionally comedic film-within-a-film musical version of GONE WITH THE WIND that is well worth your time:
In all, IRRECONCILABLE DIFFERENCES is a pretty typical but watchable late 70s/early 80s "epic dysfunctional relationship dramedy" (see also: MODERN ROMANCE, HEARTBURN, ANNIE HALL, OLD BOYFRIENDS, et al.) with an added twist of a frame story that depicts a daughter divorcing her self-centered parents. Things get weirder when you factor in that Drew Barrymore (a demonstrably neglected child in real life) is playing a neglected child and Ryan O'Neal (a demonstrably terrible father in real life) is playing a terrible father––though, oddly enough they apparently got along famously on set, with Drew writing "Ryan kept my sanity... he was very fatherly," in her memoir LITTLE GIRL LOST.
Anyway, the true gem of the film is the preceding Sharon Stone clip, which comes from a scene where Ryan O'Neal (playing a film director) is making a disastrously overbudget GONE WITH THE WIND-inspired musical called ATLANTA, in what appears to be a reference to the box office belly-flop of HEAVEN'S GATE. Enjoy.
