What makes a character (or a real person) interesting?
An article on Ozy.com reveals, "For filmmakers Elizabeth Delaune Warren and Danya Abt, quirk is key. The eccentricities and complexities that drive people also drive their documentary filmmaking.
'You take someone who’s a potato farmer in Idaho, and you expect a certain thing from them,' Abt says. 'How do they subvert those expectations?'
For Abt, the answer is in resisting the instinct to simplify and instead focusing on those very traits that don’t seem to fit the usual narrative. She believes this is the point at which a character starts to have dimension."
This works great in fiction as well.
The trick is not to automatically go for the opposite--for instance, the pro football player who is an opera buff, or the granny who rides a Harley-Davidson.
That's not to say that there aren't football players who love opera or grandmothers who ride Harleys, but it feels a bit by rote. Instead, it might be a football player whose hobby is woodworking, or a grandmother who coaches a kids' baseball team.
For inspiration, think about the quirks of your family members, your friends--or your own.
