I mentioned this film as an aside commenting on Stephen Wolfram’s piece, Quick, How Might the Alien Spacecraft Work?

I’d watched it when it first came out and was impressed, regardless of budget/special effects.

I’m watching it again now and I’m even more impressed.

You can watch it free on YouTube…

For some reason the film begins minus the opening title/credits. However, I note in the ad (above) the film is listed at 1hr. 41. mins. The film on YouTube is listed as 1hr. 52 mins.

Regardless, I think you will enjoy the film.
