An historic day. The Robinsons - John, Maureen, Judy, Penny and Will - become Earth's first family of outer space, on its way, accompanied by pilot Maj. Don West, to colonize a planet circling Alpha Centauri; however, Dr. Smith, as an enemy agent of a foreign power, means to set them on a course of doom by reprogramming the robot to destroy their ship, the Jupiter 2, eight hours in space. The unfortunate doctor winds up caught in his own treachery and hurls off into space with the Robinson party. His excess weight first throws the ship off course, then, with the robot coming to life and bashing all the controls, they all become "hopelessly lost in space." Written by statmanjeff

Did You Know?


Alpha Centauri, a.k.a. Alpha Centauri AB, is currently classified (as of 2012, at any rate) as a binary star, approximately 4.37 light years from Earth, with its two suns designated as A (the larger) and B (the smaller). Proxima Centauri, a.k.a. Alpha Centauri C, is .2 light years from Alpha Centauri AB. At one seventh the size, its sun is much smaller than ours and not visible to the naked eye, but its distance from Earth is 4.24 light years, making it the closest sun to ours. It was discovered in 1915. An Earth-mass planet had been detected in orbit around Alpha Centauri B, but, It is not in the habitable zone, orbiting very close to the host star. It's surface temperature is estimated to be 1200 °C (about 1500 K) - far too hot for liquid water and also above the melting temperatures of many silicate magmas. See more »


The news anchor at the Space Control Center says that probes have looked to other galaxies for suitable planets for colonization, but then says a planet orbiting Alpha Centauri (the star/solar system closest to Earth) is the Robinsons' destination. See more »


Will Robinson: My dad said you were left aboard when you came down to adjust the helium/nitrogen intake.
Dr. Zachary Smith: That's right.
Will Robinson: But the helium/nitrogen intake valve's on the UPPER level.
Dr. Zachary Smith: Oh? Well... Who said anything about the intake valve? It was the emergency supply I was concerned about.

Sci-Fi & Disaster

In 1997 an American family and a reluctant stowaway become lost in space.

The start of one of the greatest TV shows ever made. All 83 episodes of Lost In Space are not perfect but nearly every episode has a good moment or two that makes the whole hour worthwhile. Sometimes that good moment is a knockout bit like the teaser of season two's The Forbidden World where the Jupiter 2 crash lands on an alien planet.

If you are a fan of shows like The Outer Limits (1963), Voyage to the Bottom of the Sea (1964), Batman (1966), The Time Tunnel (1966), Star Trek (1966), QM's The Invaders (1967), Land Of The Giants (1968), Shazam! (1974) and Irwin Allen's Captain Nemo (1978) you will love Lost In Space.

Producer Irwin Allen is very much the star of anything he makes. His control-freak quirks are all over Lost In Space (but less so in season two). I wrote Irwin's IMDb Bio so if you don't know what I mean by Irwin his Bio.

The Reluctant Stowaway is one of my two favourite episodes of the series (the other favourite is The Derelict) as it is just totally outstanding from the first frame to the last frame.

A sight and sound wonder with Dick Tufeld narrations and John Williams music providing the sounds. The sights include amazing footage of spaceship Jupiter 2.

We also see Jonathan Harris at his very best as the EVIL Dr Smith.

I am both a sci-fi nutcase and a disaster nutcase, this hour covers both what more could I want?

I have many more Lost In Space episode reviews on this site.
