"Xtro may well make xenophobes of us all," proclaims this cover. It's more likely to make moviephobes of us with this embarrassingly bad cover. We're not sure what to be more frightened of, the crudely drawn brown goo that's supposed to be an alien or what looks like the kid from 'The Shining' wearing a turtleneck.

It's also amusing to see how 'E.T.' influenced early 1980s sci-fi films, as the cover adds, 'Some extra terrestrials aren't friendly." Yeah, the snarling monster on the cover was a pretty big hint.
