So what is it all about?
A research group is looking into ways of storing and retrieving information. One of the team members, Jill Greeley (Jane Asher) witnesses a ghost. This is enough for team leader Peter Brock (Michael Bryant) to try and analyse this in a rational manner. He sees this as an opportunity.

So orthodox science cannot always come with a rational explanation. This programme looks at science and belief. It is not asking us to choose one system over another. It is acting as entertainment. If there is supposed to be any message in this, it is to keep an open mind about things that we cannot explain at once.

The interplay of the various characters is very good. The team leader Peter Brock is not a person one can like very much. Jill Greeley is not the sort of person who screams and waits for the hero to save her. Nigel Kneale has a habit of writing strong female parts. The performances are all very good in my opinion. You can get interested in the characters and feel for them. The sets were all cutting edge for 1972. They may appear to be a little old fashioned to us now. The acting may appear corny to persons who are used to the modern films, the sets quaint, the effects poor and the direction may appear to be rather soft. Undoubtedly if this were to be remade a lot more would need to be spent on effects, though I am not sure who they could get to give as good performances. It is the ending that I can remember very well and is one of the best endings of any ghost type story I have seen.

To access the film through a computer DVD drive you have to agree to a specific licence. I have had problems with something like this previously so I didn't. However the scripts are in Adobe Acrobat PDF format so can be accessed directly from a computer by clicking on the icon and exploring. If you do not have this programme, a copy is provided on the disc. Apparently the road was produced in 1963 but I have been unable to trace any film copies. It again appears to be a rather ghostly story.
