This would make a great stage play. It's even split into three theatrical acts, which are so easy to imagine on stage that I was wondering if that's how this started and this is just a film adaptation.

ACT ONE (10 minutes) = people see a zombie wander into someone's house... so they all get excited and start throwing around ideas about what to do next. The house's owner jumps through an upstairs window to get away, but they just want to stop him from doing anything silly like calling the police. (It's five years since Japan's Great Zombie Panic and there are laws about what to do if you see one.)

ACT TWO (50 minutes) = they gather in a neighbour's house and discuss their next move. 1. A teenage boy (Riku Hagiwara) just wants to film it on his phone and become big online. He's happy and enthusiastic, but he'd probably get out his phone and start filming if people were getting killed in front of him. 2. That grumpy window-jumper (Akihiro Kakuta) is theoretically the only sane man, but in practice felt to me like the "tsukkomi" half of a manzai comedy duo. He's irritable, yes, but surely the situation calls for more than "irritable"? 3. His wife (Rie Tomosaka) was for me the film's funniest character. She's cute, happy and amusingly cheerful even when discussing flesh-eating undead. She's glorious. 4. An unsuccessful businessman (Yoshiyuki Morishita) wants to sell it for money. They're getting rare these days, so there are specialist collectors. Some people keep zombies as pets. 5. One woman (Marie Machida) used to be the zombie's wife. 6. A medical student (Reiya Masaki) thinks it's a desirable specimen.

...or so they say. There might be some lies in there.

ACT THREE (30 minutes) = they've decided. We'll go into the house! My goodness, they're idiots. If you find a zombie, don't play with it. Also, there's the odd hidden agenda.

I loved this one. It's witty and clever, although admittedly low-key as either a zombie flick or a comedy. ZOMBIE FLICK: the zombie's amusingly stupid even by zombie standards and spends most of the film unable to attack because it's stuck somewhere. COMEDY: it's not about jokes, but instead an ensemble character piece about people discussing deeply inadvisable choices. It's playful, e.g. the twins photo where the "girl" is obviously the male actor in drag. Its cast is strong too, except to some extent Akihiro Kakuta. Rie Tomosaka is wonderful, while Yoshiyuki Morishita I know from other things.

I'm astonished that this is its writer/director's only significant screen credit. There are lots of zombie comedies out there, but this deserves to be better known. (If you want a list of them, there's even a wikipedia page for "zombie comedy".) If you're a zombie fan, I'd definitely recommend this.
