“I have brought upon the Earth what is possibly the most terrible thing ever known. What came out of that rocket was not a man. It had been men — a human amalgam possessed by the thing that entered into that rocket over 4 million miles away and transformed them. It had their brains, their faculties. But over the last three days, it has developed the means to existence on this planet — the means to ensure that it only shall exist.

In April 2005, the “experiment” was repeated on BBC 4. Nigel Kneale’s original script was adapted, with his assistance, and updated to allow for changes in social mores and geopolitics as well as our increased knowledge about space and space travel that simply wasn’t available 50 years earlier. Instead of six 30-minute episodes, the story was compressed into one show approximately an hour and 40 minutes long.
But one thing remained unchanged: Quatermass was enacted and aired live. The BBC (nor anyone else, really) has not regularly presented live television dramas since the ’60s. It’s a style that was common in TV’s earliest days, when performances were a sort of combination of theatrical plays and radio drama, but it has long been abandoned in favor of videotape or film. Live TV is like working without a net.
