At the end
 of your excellent discussion on the usage of script versus screenplay, you
 make a comparison between one page of a screenplay and one page from a TV drama.
 Format-wise, they may be similar, but as the mediums are different (television
 for all its visual acumen is very much a dialogue based medium compared to
 film) would this not be apparent in the writing on these same pages under comparison?

In certain cases, yes. A script for "Law and Order" is almost entirely
 dialogue in the second half, when the court case kicks in. "The West Wing" is
 all talking, all the time. If you looked at any one page from these scripts,
 you might be able to guess that it’s a TV show.
But a page from "Alias" or "Angel" or "Smallville" looks
 and feels exactly like a feature. With the exception of act
 breaks, the flow
 of words on the page is no different than a 120 page screenplay. 
That’s one reason why I would highly recommend any budding screenwriter try
 writing an episode of their favorite one-hour drama. It’s a great exercise
 in getting comfortable with the challenges of the format. In fact, the very
 first script I ever "wrote" was an episode of "Star Trek: The
 Next Generation," which I literally transcribed from tape. (I was 19 at
 the time. The episode was "Galaxy’s Child," teleplay by Marice Hurley,
 story by Thomas Kortozian.) For the cost of a few hours, I learned a lot about
 scene length and story pacing, and it got me over my fear of screenplays.
