While seeking shelter from a cosmic storm, Penny and Dr. Smith discover a mirror composed of solid platinum. Following Debbie the Bloop through the lost-in-space-the-magic-mirrormirror, Penny enters a mysterious dimension occupied by a boy (Michael J. Pollard) afflicted with Peter Pan syndrome. As Penny struggles to return to her family, Dr. Smith—having fallen through the magic mirror—assumes that all of his surroundings are the result of a psychotic episode.

Despite emphasizing fantasy-themed subject matter over hard science fiction, “The Magic Mirror” deserves its reputation as a classic installment of Lost in Space. Especially wonderful is the performance of Angela Cartwright, whose character begins developing into a mature, thoughtful young woman at this point in the series.



lost-in-space-the-magic-mirrorDuring the sequences wherein Penny, Debbie, and Dr. Smith remain trapped inside the magic mirror, a blurring effect serves to accentuate the surreal, dreamlike nature of the pocket dimension—a technique that, when complemented by John Williams’ musical arrangement (originally featured in “My Friend, Mr. Nobody”), delivers a haunting and unforgettable impact.



When wandering through the “mirror” universe, Dr. Smith rationalizes every bizarre, frightening, and incongruous event from a psychological perspective. lost-in-space-the-magic-mirrorThough mildly amusing, the antics of Dr. Smith detract from the solemn, thought-provoking message at the heart of this offering.

Also worth criticizing is the furry, one-eyed monster that attacks Dr. Smith during the climactic scene, which, despite benefiting from a serious tone, may unintentionally prompt snickering from the audience for obvious reasons.



lost-in-space-the-magic-mirrorA metaphor for the trials, challenges, and insecurities that plague every young woman during her pre-adolescent years, “The Magic Mirror” should be commended by fans of Penny’s character. Specifically, the boy played by Michael J. Pollard (whom science fiction enthusiasts will recognize from his portrayal of Jahn in Star Trek’s “Miri”) embodies the temptation to remain in a state of perpetual youth, which contradicts the desire of Penny to accept responsibility as would an adult member of her family—a subtle, well-written commentary on a painful aspect of life.


Concluding Comments

“The Magic Mirror” is a touching episode of Lost in Space. The ridiculous behavior of Dr. Smith does, however, occasionally undermine the interactions between Penny and her host (likely a manifestation of Penny’s id).


Overall Quality: 8/10

  1. Judy was such a victim of the times! She spends most of her time thinking about her appearance. Fixing her hair, wishing for new dresses and fishing for compliments from Don. Let’s not even get into the character assassination they did on her in A Trip to Hades. Writers would never get away with writing a woman this way today (and thank God for that)

    • Because women today are hired to pick up 60 pounds trash cans, to work fixing powerlines and are summoned to go to war whereas the men remain at home looking after the kids, right?

  2. This is my number thirteen ranked episode for the classic B&W season and also for the entire series overall..

  3. After 50 years of watching this, I still do not know if it was all a dream by Penny as Dr. Smith surmised at the end of the episode.

    It doesn’t really matter, it’s a powerful episode.

    At this point in my life I think I’d prefer to be that boy and never have grown up because as Dr. Smith said in another episode….”Don’t be in such a rush to grow up, it really isn’t worth it”.
