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.
