After all these years, I finally caught "Five Million Years to Earth" in its entirety. I always seemed to miss the first 30 minutes or so. A nifty lil' sci-fi thriller released by Seven Arts/Hammer, this film was originally titled "Quatermass and the Pit". It was based upon a BBC presentation in six parts televised in 1958. It was retitled for American audiences as the titular character was largely unknown in the US. Andrew Keir played Bernard Quatermass and is probably best remembered for that role. (You may recall he replaced Peter Cushing (when he had to bow out when his wife took ill) in 'Blood from the Mummy's Tomb" discussed a few pages back.
It has been debated among some genre fans producer Barry Letts may have gained inspiration from Quatermass when he became the showrunner for "Doctor Who" and Jon Pertwee assumed the role. Certainly, it's easy to imagine Quatermass as the Doctor butting heads with the military. Of course, if it were the Doctor, his vast experience and knowledge would have lead him to "the answers" in relatively short order. Quatermass, being human, a learned one, but still human, we as the audience can more easily follow him as he tries to solve the mystery of "the pit". He's as much "in the dark" as we are in the beginning.
As I noted, the movie was based upon a BBC 6 part series and from what I've read during some casual research is quite faithful to the television broadcast. That's because both productions were written by Nigel Kneale, who created the character. I can't personally attest how similar they are, but I might by the end of the evening. You see, both are available for viewing on-line. Yes,unlike many episodes of Doctor Who, the BBC TV version of "...the Pit" still exists. In fact, I've paused it to compose this post. Aww, heck, you can judge for yourselves. Here are the two versions.
