This is way before my time but when a programme is this good it matters not. I used to watch this sometime in the 1980's with my Dad and it was one of my favourite programmes at the time but it wasn't this series, it was a later one because I can remember it being in colour, but anyway the presentation and music (very uplifting for something so dark) was exactly the same as this. Although I can't really remember all of the stories from those colour episodes, there was one in particular that involved somebody accidentally being buried alive after a plan went wrong and it put me off ever wanting to be buried when I die.
I love the way this series is presented by Alfred Hitchcock, he was a national treasure and I particularly like his witty remarks before and after each episode I really hope they release every series of this on DVD, it would be a tragedy if it wasn't. At the time of writing, this as to be one of the best value for money DVD boxsets ever at (at the time of writing) just under £9. There are 39 episodes at roughly 23 minutes each and a good variety of stories all with some kind of twist at the end. I don't think that this is as well known as say for example The Twilight Zone (another classic that as aged beautifully) or to younger people like myself, but if you like that and anything similar, then even at over fifty years old (and as I have already mentioned this is way before my time) I would recommend this classic programme to anyone.
One last comment is that I am sorry to say to the person asking that there aren't any subtitles on this particular series which is wrong, as I think that they should be on all DVD's as standard but I am not sure about series 2 and whether they will be on the remaining series (if they are ever released), so fingers crossed.
