Courier Prime from Quote-Unquote Apps
Sally Kerrigan, writing for Typekit:
Screenplays are traditionally written in a monospace typeface, which generally means Courier. Frustrated by this status quo, John August at Quote-Unquote Apps set out to build “the best damn Courier ever,” enlisting Alan Dague-Greene for the design. Courier Prime is optimized for 12-point display, and works nicely onscreen or in print. Don’t miss the gracefully-done italics, either.
