Singularity (1970)

Sinopsis

A crash landing leaves an astronaut stranded on a desolate planet, he attempts to phone for help. Instead, he’s met by a robotic, automated voice calmly informing him: “...unfortunately, all our operators are busy right now...” Stuck, with no other means of communication, he has no choice but to wait. Surrounded by an endless expanse of sand and rocks, boredom quickly sets in, forcing him to find creative ways to pass the time. As the monotonous hold music plays on, isolation begins to wear him down, and he’s left desperately hoping for a response that can’t come soon enough.
