I couldn't find a way to get a URL. If I am watching a movie, the URL has a lot of tracker info and perhaps session ID, so I don't want to send that. I could only tell the person to "search" by some title... it can work but it totally defeats the functionality of Web and URL.
I found a way, which is to use a link to the actor or actress or director: https://www.netflix.com/browse/person/39020
but is there a way to get a simple URL to a movie or TV show or episode?
