A remake of the original 1950's serial (which was also remade as a movie by Hammer in the 50s). This time rather than being a 6 part series, its condensed down into one movie, but interestingly, also like the original, it was broadcast live. It was remade as part of a series of productions in the mid 2000s by the BBC, looking back at their older work, filming styles and storytelling techniques.
Due to it's live broadcast nature, there is a lot of this that plays out almost like a stage play, but with many 21st century methods to up the tension, as well as insert shots to give the actors time to get to their next markers/location.
It's still…
