This movie tackling themes of prejudice has several strong points. Initially, it establishes a familiar starting point. The director introduces William Shatner to the story, seemingly as a lead character, but he swiftly transforms into someone antagonistic. The setup is reminiscent of "Women of Dolwyn," where Richard Burton appears in a similar fashion; however, his character wasn't nearly as unpleasant as the one played by Shatner here. A distinctive element lies in the casting choices. One anticipates Shatner embodying the progressive viewpoint and Leo Gordon representing prejudice, but the film subverts that expectation. That unexpectedness is genuinely what makes this movie appealing. I’m uncertain if audiences a century from now will recognize that aspect, but I believe they'll still grasp the underlying feeling, because it seems the director deliberately selected Shatner and Gordon for their individual "presences" to surprise viewers.
