In 2013 the six part Jon Pertwee story, The Mind of Evil, was released on DVD in colour.
Nothing surprising about that you may think, but after the original colour tapes were wiped in the mid 1970’s only black and white film prints remained. A process called chroma dot recovery, developed several years ago, was used to restore the colour embedded in episodes 2 – 6.
Episode 1 didn’t have chroma dots though and the cost of computer colourisation was far too high. Things looked bleak until Stuart Humphryes (otherwise known as Babelcolour) entered the fray.
This short video briefly explains the painstaking work that brought the first episode back to colour as well as presenting the best moments of the episode in a stylish trailer.
