No surprise, I have been spelling it wrong. It's not ruku.
If you have a roku unit the channel is free. I think the unit was about $150 when I bought it for my wife a few years ago, there were a couple for less and one for more. Hers is the small black square similar to the Apple TV unit it replaced with an hdmi cable. She uses it for Netflix and Disney +
Amazon has one for $39.95 right now, it looks like a USB stick. No idea if it is as good as the bigger unit. I would think there is a reason they make a big one that is more expensive though.
That was the first time I clicked on the roku channel..
http://www.roku.comThey showed two brief commercials at a time a few times, possibly five, during the movie.
I will search up Terrence Hill, that might be the only one on there. There was other westerns but that caught my eye and I fired it it. Very pleased I did.
