Did You Know?


Dr. Smith tells Will he won't be able to vote until he's 21. While that was true at the time the show was filmed it wasn't true for the time the show took place in. At the time of production no could have known that in 1971 the 26th Amendment would pass and lower the voting age to 18. See more »


When his father comes back after his trip, Will tells him about the horrible looking creatures/aliens that came into his bedroom. Will couldn't have seen them from where he was standing on the top shelf in his closet when they came in. See more »

A Very Colourful Bunch Of Guest Stars (Guest Aliens)
25 July 2011 | by See all my reviews

Smith turns the Jupiter 2 campsite into a resort for aliens.

To me, Irwin Allen's Lost In Space/Time Tunnel/Land Of The Giants shows demand a good guest cast so you can imagine how thrilled I would be with this bunch in Two Weeks In Space.

From the sexy/amusing female goddess Edy Williams, to the super-silly Fritz Feld (Mr Zumdish), and finally the two alien guys who go a bit funny at night!

I like everything about Two Weeks In Space: the alien costumes, the inside of the alien spaceship, the combination of comedy and drama, Smith fainting towards the end, the climax, the stock music lifted from season one's The Derelict.

The hour begins with a totally straight teaser, then moves into lighter elements in act one. Then it soon goes back to straight drama for a while. A knockout!
