I wouldn’t describe myself as a hero; I certainly don’t feel like one. I simply tried to do what was possible, taking things slowly, moving forward incrementally. Chattahoochee is the work of director Mick Jackson and writer James Cresson (credited as James Hicks). The cast includes Gary Oldman, Dennis Hopper, Francis McDormand, Pamela Reed, Ned Beatty, and M. Emmet Walsh. John E. Keane composed the music, and Andrew Dunn was responsible for the cinematography. The story unfolds in 1955 Florida, where Korean War veteran Emmett Foley (Oldman) experiences a mental breakdown and finds himself confined within a “maximum security” psychiatric institution. While there, he observes instances of patient mistreatment and exploitation. It felt reminiscent of One Flew Over the Cuckoo’s Nest. This intense story centered on incarceration falls short because its script is weighed down by familiar tropes that prevent it from reaching the heights of other films exploring similar themes of how mental health patients are treated poorly. Emmett's efforts to reveal the terrible conditions inside the institution where he’s held, and his developing connection with Benson (Hopper), along with complications in his relationship with a woman on the outside (McDormand), do manage to hold your attention. Despite strong performances from the main actors, the writing and direction are somewhat conventional, leaving you wishing for earlier, more accomplished films of this type. 6/10
