Given the question: Given the below context:  Kurtwood Smith plays Myron Castleman, an everyman stuck in a loop that forces him to constantly relive the same hour of his life over and over, being the only person aware of this. During one loop, he discovers that a scientist named Nathan Rosenbluth has predicted an event that matches his experience. Castleman calls him and explains what is going on, however, Rosenbluth is highly skeptical of his claims. Over the next loops, Myron struggles to get into contact with Rosenbluth again, and in the process becomes frustrated to the point of screaming at his secretary and throwing his suitcase into traffic. Eventually, he does manage to talk to Rosenbluth, who initially dismisses Myron as crazy until Myron describes the transition as the scientist had predicted (including the phrase "Consciousness is an independent variable," which is central to Rosenbluth's theories). The professor sadly informs Castleman that there is nothing that can be done, causing Myron to become hysterical and shoot himself. There is a brief pause until Myron finds himself back at the beginning of the loop, realizing that he is trapped for eternity.  Guess a valid title for it!
The answer is:
12:01 PM (1990 film)
