Thanks for explaining this. I was having trouble to understand what was the concrete problem this font was trying to solve. That makes a lot of sense. Especially the standardization of text length to determine actual playtime.
I don't see the relationship between text length and actual play time. Plays and movies aren't just people spewing lines non-stop. Text/playtime varies a lot between a Tarantino movie and something like Mad Max: Fury Road. It seems like a pointless metric. And while I like courier in general, I thought typography experts disliked it because it's not as readable as proportional fonts. I'd expect readability to be impo…
Supposing I hand you a 90 page book and ask you roughly how many words are in it. How are you going to answer that? People hand round paper screenplays, or bits of screenplays, all the time, especially on set. It's much more practical for lots of purposes. Abandoning the minute-per-page rule of thumb (or equally importantly pages-per-shooting-day targets) would create way more problems than it solves.
However, it's also true that if you receive a screenplay that's not in standard screenplay format, it's a very reliable indication that the writer doesn't know what they're doing. Not a perfect heuristic, but there are maybe hundreds of thousands of spec scripts in circulation of which a few dozen a year get picked up by studios. So they can afford to be picky.
Bonus trivia: As it happens Fury Road is a very rare case of a movie that was originally developed as a storyboard, and converted to screenplay format for production purposes. Apparently you can do that if you're George Miller.
