I am trying to find out the name of a movie that I saw as a kid back in the late 50's or early 60's. The terrifying image that stayed with me all these years is of a gigantic quivering sponge-like alien that lives in a big enclosure of ammonia. This movie scared the daylights out of me and I would like to see it again.
Anyone recognise this imagery? Please help.
Th Crawng Eye comes to mind, although it lived in a radioactive cloud. One of the goofier 50s flicks, but a load of fun.
Sounds like you're thinking of ENEMY FROM SPACE a.k.a. QUATERMASS 2. The aliens live in gigantic domes with ammonia for atmosphere. They do indeed look like a gigantic quivering sponge. Here's a review of the movie with a couple of pics that may spark your memory.

Quatermass part 1 was good. Part 2 should be a whole lot better.
