Hoping to prove themselves worthwhile, space hippie Ilan (Dan Travanty) and his merry band of misfits embark on a mission to destroy Kromah—a planet that, if allowed to continue on its current trajectory, will soon collide with the hippies’lost-in-space-collision-of-planets home world. Trapped on Kromah until Don and John can finish repairing the Jupiter 2, the Robinsons plead with Ilan to delay his plans for the time being. Though unmoved by the potential loss of innocent life, Ilan and his gang encounter a threat of their own when Dr. Smith—having inhaled a mysterious gas—develops curly, green-colored hair and superhuman strength.

A slapdash parody of the hippie movement, “Collision of Planets” would best be avoided by the majority of science fiction fans. Those with a high appreciation for nostalgic elements may, however, wish to view this episode for its miscellaneous pop culture references (i.e., Samson the Strong, psychedelic music, and the Incredible Hulk of superhero fame).



lost-in-space-collision-of-planetsGerald Fried (an occasional composer for Star Trek: The Original Series) should be commended for his mesmerizing and hypnotic arrangement, which serves as a fitting, albeit simple and repetitious, soundtrack for Ilan and his far-out friends.



Upon absorbing an alien substance, Dr. Smith adopts a threatening demeanor to complement his newly enhanced physique, thus evening the odds between the Robinsons lost-in-space-collision-of-planetsand their uncouth aggressors. That being said, viewers may struggle to accept the imposing Dr. Smith—a cross between Marvel’s aforementioned Hulk character and an Oompa-Loompa from Willy Wonka’s chocolate factory—as anything more than a silly plot device. (It should also be noted that a similar concept had been employed more effectively in “The Oasis,” wherein Dr. Smith grows to a gargantuan size after consuming a piece of extraterrestrial fruit.)



lost-in-space-collision-of-planetsSimilar to “The Promised Planet” from later in season three, “Collision of Planets” fails to include a meaningful statement on 1960s youth culture. Nevertheless, a veiled commentary on the consequences of degenerate behavior (e.g., experimenting with mind or body altering chemicals) is present in this offering.


Concluding Comments

“Collision of Planets” is a juvenile, loosely coherent satire on two unrelated subjects (i.e., hippies and Biblical heroes). Therefore, viewers would be wise to search elsewhere for a compelling and well-written science fiction piece.


Overall Quality: 3/10

    • Oddly enough, this one was among my favorite episodes as a child. Isn’t it funny how our perceptions change over time?

  1. This is my number nineteen ranked episode for the psychedelic and far out, all over the place, highly inconsistent and relatively overrated, shortest final colored season..

  2. Season Three’s relatively impressive first-third of the season has passed, and now the quality goes significantly and rapidly downhill to the opposite direction. While this episode is quite fun and amusing story (well, like all of them), really the only redeeming factor here for me is guest star Linda Gaye Scott as the sultry ‘hippie girl.’

    The guest incidental background scores from composer Gerald Fried are kind of weird and less than stellar. Still as always, the music matches the storyline very well. I, too, liked this one more as a youngster.

    Dan Travanty does put on a good show..

  3. This episode is an excellent example of the over-the-top story lines for Dr. Smith. I wonder if Jonathan Harris thought,
    “I can’t believe the script writers are having me do this! Oh, well, as long as I get my paycheck, I’ll do whatever.”
