20 Things You Somehow Missed In Alien

20. Milk Crates

The Alien credits include, amongst other things, a huge thank you to the UK's Milk Marketing Board. Most people assume that the liquid which comes spurting out of Ash is milk but, owing to how quickly it would go off under the studio lights, this isn't the case.

Instead, the thank you concerns the hundreds of milk crates that the board supplied the studio with. These crates, once painted and upturned, comprised pretty much the entire structure of the Nostromo's corridors. With the floors and large parts of the walls constructed from them.
