Last year, for Halloween, Channel5 in the UK, shared a documentary titled "Stephen King : Master of Horror"

But it hasnt been released in the USA. Until now!

It can be seen on the Reelz Channel.

Someone shared to me, on my Club Stephen King website, that via DIRECTV, for instance, it is on channel 238, and it would be schedulted twice today at 8PM and 11PM Central Time.
As well as on September 29 at 4PM Central Time.

There is a video on the following link, but I cant access to see if it's a trailer of the entire documentary.
