Commentary by writer David Rudkin, director Alastair Reid & TV historian Richard Holliss (in English)
Notes:
Now this was interesting! And strange, or... weird might be a better fitting description. :-O Regarding the DVD presentation, it's quite poor by today's standards, but the atmosphere of the film itself will soon make you forget about such earthly trivialities. ;-) And to make the whole thing even more mysterious, the cover states the running time as "xx mins approx."
*it says "16:9" on the cover, but it's a mistake **difference between channels is -74.13 dB (0.02 %)
