not as easy as it seems, eh? tron - now, isn't there an office outside at the start and maybe some grass then?

or honey i shrunk the kids :D

Batman Returns

bladerunner

(thats not a blade of grass, before anyone asks....)

Yes, but Bladerunner is based on "Do Androids Dream of Electric Sheep" by Philip K. Dick. In the book, Deckard and his neighbours let their animals graze on the roof.

So I reckon that there is "grass by association" in Bladerunner.

A film by Derek Jarman called Blue.
1 hour 17mins and all you see is a blue screen with him talking. No grass, no people, no nothing but Blue.
Very odd film

RE: Blue screen film

Sounds like someone forgot to turn on the imaging machine :D:D (i.e. blue screen TV technique).

The Lawn Mower Man :D
