Keep Watching the Skies! continues at Trailers from Hell with director Ernest Dickerson introducing Hammer's "The Creeping Unknown," starring Brian Donlevy and Jack Warren as a professor and inspector trying to get to the bottom of a mysterious rocket crash, which has left two crew members missing and one mutating into a monster.

This was the US title of the Hammer screen version of Nigel Kneale’s six-part BBC sci fi serial THE QUATERMASS EXPERIMENT, which had been a nationwide smash and led to three feature film sequels. Director Val Guest shoots in a flat newsreel style that imparts a semi-documentary, almost newsreelish quality to the proceedings. Since restored to the original running time, it’s now available under the British title.
