Its from the 90s. About some green aliens who try to invade the earth. The aliens wear human skin outside them selfs, and they bend theirs knees the wrong way. And they can jump really high.

I remember one scene where an alien disguised as a man got into a house and placed a little thing in the house that swallowed everything inside (like a little black hole).

There is one guy who finds out about the aliens in human skin, and he follows one of them and gets inside the alien 'base' where he is exposed and chased around.

Thats about what i remember...

Could be "The Arrival", starring Charlie Sheen.
