Rolling Thunder (1977)

Charles Rane, a Vietnam veteran, returns a celebrated hero after enduring years of captivity. Yet, the accolades ring hollow against the profound scars of war. As Rane struggles to reintegrate into a society he no longer recognizes, his inner demons begin to manifest, pushing him toward a precipice of despair. This is not a tale of the undead in the conventional sense, but a stark portrayal of a man haunted by the ghosts of his past, a walking casualty of a conflict that continues to wage within him. It is a chilling exploration of post-traumatic stress, long before zombies dominated the cinematic landscape.
