Right now I'm thinking two things...
1. The film came out before 1975
2. The names are going to be more familiar as we go. Antares, I know you've had a rough go with the people here whose memory for classic film doesn't go back further than twenty years. I'm thinking there's a giveaway name near the end. Considering your history, it might even be a name that's part of if not the entire title of the film.
