一个年轻的拿破仑军官追踪一个神秘的女人而来到一个年迈男爵的城堡，在那里他发现这个女人是听命于一个老巫婆，其最终目的是迫使男爵自杀…… Roger directed for two days on a set left over from a previous production, and without a proper script. He hired Francis Coppola to write a script and finish the picture. After five weeks of shooting, Roger fired Francis, and hired me to finish the picture. Jack Hill was hired to write a new script with me. A lot of what Francis shot was thrown out, except for the stuff with the witch from WIZARD OF OZ. (Dorothy Newman), and I finished the picture in five days of shooting. All of the interiors are Roger's (with the exception of Francis's witch's lair), and most of the exteriors are mine. To the best of my recollection, and contrary to legend, Jack Nicholson did not direct any of the film.
观众对《恐怖古堡》的评价两极分化，一方面认为剧情离谱、演员表现惊艳，另一方面认为编剧粗制滥造、剧情不合理。
该片以其深刻的战争描绘和人性的探讨赢得了观众的广泛赞誉。剧中的视觉效果和演员的精湛表演让人深刻体会影片的精彩之处。
它是一部值得一看的电影，通过其故事和表现手法，让观众反思剧内向观众表达的意义和人性的复杂！
这是一部非常特别的影片，没有大开大合的剧情，没有博人眼球的类型元素，没有贯穿到底的故事脉络。像是一杯温开水，看似平淡，却喝起来十分解渴。
说真的，《恐怖古堡》看完后我真的是久久不能平静！因为这部影片确实带给人的震撼太大了！不论是剧情节奏，还是剧情尺度，都让人不敢相信这是美国剧的水平。
