Quatermass and the Pit - the trailer

This is a really fun trailer for the movie Quatermass and the Pit (1967).

The movie starred Andrew Keir as Quatermass, James Donald as the actual hero of the piece, Barbara Shelley and Julian Glover.

There's an homage to the movie Them! here. In one scene a terrified man screams, "They're coming. Them! Them!" he's referring to the Martians of course, not giant ants.
