Today's tip: catchier titles get read sooner and instill more goodwill.
Your title is the first thing any reader will see. In some cases - who am I kidding? - in EVERY case it will determine which script they pick off the slush pile next. A good title should give a sense of the genre, hint at the premise and be memorable. Bad titles tend to be generic, bland or pretentious.
To give you an idea, I went over to ScriptShadow's site and took a look at the titles of the script's he's recently read. Here's what I'd pull from the reader pile, and here's what I'd leave for the next schmuck to get stuck with (after doing a check on the page counts of course. If any of the "bad" ones were 90-100 pages, I might take them anyway.)
Good titles:
She's Out of My League
Van Damme v. Seagal
The True Memoirs of an International Assassin
You Again
I Want to F___ Your Sister
Bad titles:
Taxonomy of Barnacles
Gone
Villain
Conviction
Dubai
