I've no idea why it's only 45 minutes long. It doesn't feel made for TV, but never mind. It's cheap, it's fun and it's worth watching if you can find a copy.

A handful of friends are in Okinawa to shoot a low-budget zombie flick. The crew's so small that it would be flattering even to call them "independent filmmakers". A bloke with a camera decided to shoot a film and recruited some mates. It's on that level. The only scripted scene we see our heroes shoot features a zombie being defeated by dancing, although I was amused by the zombie actor asking for feedback on his performance.

Anyway, a real zombie appears and eats someone. It also participates in a zombie roaring contest when our amateur actor doesn't realise he's looking at the genuine article and thinks his thespian status is being challenged. I laughed.

Imagine you're a moron shooting a no-budget zombie flick. What might you do on finding a real zombie wandering around the shooting location? Yeah, you guessed. They follow it around for gonzo filmmaking, not paying enough attention to the fact that they're occasionally getting bitten.

There's a scene so daft that your jaw will drop. No, not in the film-within-a-film. It's meant to be real. The zombie pulls off someone's arm (which in real life requires somewhere between 3-20 tons of force, about a thousand times greater than a punch). The victim asks how he looks, gets up, grabs a spade and decapitates the zombie. His severed arm stops bleeding after only a few seconds, instead of the more realistic outcome of massive gushing from severed brachial and other major arteries until you bleed to death in a few minutes. Our hero isn't even in pain. He swaggers. My best guess is that he was already part-zombie thanks to earlier bites and so his blood supply wasn't operating properly to start with.

Over time, the zombie count increases. It starts looking unlikely that our heroes' filmmaking efforts will reach the outside world.

I enjoyed this one. It has zombie fights and blood fountains by special effects maestro Yoshihiro Nishimura (Tokyo Gore Police, Vampire Girl vs. Frankenstein Girl). However, it never feels gross or unpleasant because our heroes are too happy and excited about filmmaking to notice when they're, say, splattered from head to toe. None of it's scary in the slightest, but it's amusing. Sometimes it's funny. Its running time works, letting it really go for one simple, straightforward concept without wearing it out or overstaying any welcomes. The severed arm is bonkers, but also a trash-watcher's entertainment highlight. You won't forget that scene, anyway.

This one's a laugh, with exactly the right ending. It's far better than I'd expected for a film I'd had to look so hard to find.
