Winnipeg playwright – who is now working in New York - Vern Thiesen, explained this one to us at a drama workshop.

The way to get your play produced is to make sure you have roles that an actor would kill for.

And not just the main character – the secondary characters too.

For example – in Romeo & Juliet all of the characters are great from an actor's point of view. Not just the titled pair, but also Juliet's Nurse, who is funny & dramatic; Juliet’s father, Lord Capulet - Romeo’s friend, Mercutio - and the fiery Tybalt. All are excellent.

This applies to any writing - would someone relish the chance to play your characters? If yes, great!
If no, it's time for a re-write.
