I rate this episode ★★★★★ for EXCELLENT. Another terrific episode that defines what CBSRMT is all about! A Fantasy-Mystery, written by Victoria Dann, where an Alien haunts the main character from within her body. The story puts you on the edge of your seat. Not just from questioning on how to solve the problem, but a surprising twist at the end on what happened to the Alien. A science fiction story that's so good, it would've been perfect for a TWILIGHT ZONE episode. The title is suitable, but other titles could've worked such as "What Happened On The Athena One Probe," "Body Share," "The Other," "The Unwelcome Guest," or even "The Invisible Invader." SPECIAL NOTES: The first actual woman in space, was Valentina Tereshkova in 1963. And if you have the CBSRMT Episode Guide Book, they made a typo where they put Sam Dann's name as the writer instead of Victoria Dann. The sound effects of the music playing in the restaurants, car engines running, door buzzer, footsteps, car horn, box crate locks, tires screeching, car crash, ambulance sirens, beeps at the hospital, tubes and flasks, dialing of the rotary phone, pressure chamber, and the steamed heat were very essential to this mystery tale. The music was phenomenal, especially the foreboding tunes when the Alien had to speak to the main character. In our Host's Prologue, E.G. Marshall begins with the topic of outer space where a thousand mysteries, in the infinite universe, yet to be solved. In ACT-1, the question of "Who are you?" is a philosophical context. In ACT-2, not only he asks if Man is alone in the universe, but quoted John Boyle O'Reilly who said, "Be silent and safe-silence never betrays you." In ACT-3, after discovering the where a bouts of the Alien, E.G. Marshall does a play-on-words that things have "cooled" down for our main character, but things are "heating" up for the other. In his Epilogue, he quoted Sir Francis Bacon who said, "If a man be gracious and courteous to strangers, it shows he is a citizen of the world, and that his heart is no island cut off from other lands, but a continent that joins to them." A perfect quotation that provides an essential lesson in this episode. What was also essential, was the cast: Phyllis Newman (as Dr. Margo Gordon), Marian Seldes (as the Alien), Lloyd Battista (as Professor Harry Freeman and the Truck Driver), and Hans Conried (as the Cab Driver and Owen). The 2 male actors played beneficial roles. But it was our 2 leading ladies who stole the show. Check this episode out for it is one of the best Sci-Fi tales that can't be disregarded. And check out Phyllis Newman's other performances in #0646-REUNION FEVER and #0683-THE KINGDOM BELOW. Until next time…pleasant dreams. =^D
