This category covers anything which might be expected to occupy a full evening's entertainment.
We have set the lower limit at 60 minutes - thus there is an overlap between long one-act plays and short full-length plays!
(Note, of course, that the run-times are estimates from numbers of words in the scripts.)
The Full-Length Play search category just constrains length. Use the genre search (and other constraint groups) to be more specific within the full-length category.
