If you're up for seeing what a former truckdriver can do with a budget of 20 grand provided by a group of Californian dentists looking for a quick tax write-off, cue up James Cameron's first film, Xenogenesis. If you can get through all 12 minutes of it on YouTube, you may be as fascinated as I was to observe how Cameron used much of the same themes from this in his later works; dystopian future, cybernetics, giant weaponized machines and strong female leads. It's the project that ultimately propelled Cameron into his film-making career. And to later to become one of the successful film directors of all time.
The film, while it showed off Cameron's designs, is hard to measure up by any of today's standards (obviously). The sound effects are wacky, acting is weak and you got a lead white male character by the name of "Raj". That said, you're not watching it for any of those things. This was in fact a test movie created by Cameron in hopes of attracting investors turn this into a full length feature film. Well, that didn't happen but instead got him noticed by Roger Corman, who hired him as art director and visual effects (miniature design and construction) for his film Battle Beyond the Stars (1980). What is also cool to note is that the giant robot cleaning machine is very similar to the large tank in the opening scene of The Terminator (1984) - you know, the one that's plowing over all those human skulls? He even adopted the same low angle shot of the tank wheels in both films. Interestingly, those tank wheels as I've just discovered are called "bogies".
If you're a fan of James Cameron, or just want to appreciate how far we've truly come in special effects, I would recommend you spare 12 minutes of your life to give Xenogenesis a watch. Then maybe ask yourself, could I make something better with $20,000?
