Among the winners at the 81st annual Golden Globes on Jan. 7 were Christopher Nolan, Lily Gladstone and Da’Vine Joy Randolph. They’re a multi-talented trio — and, interestingly, all are left-handed, as are many of that year’s nominees including Colman Domingo, Julianne Moore and Andrew Scott.

August 13 is International Left-Handers Day, a time to celebrate everyone who’s a southpaw. Estimates say about 10% of the population are lefties, so they seem to be over-represented in showbiz.

Here’s a small sampling: John Chu, Thierry Fremaux, Vince Gilligan, Whoopi Goldberg, Mark Hamill, Hugh Jackman, Scarlett Johansson, Nicole Kidman, Jennifer Lawrence, Paul McCartney, Keanu Reeves, Julia Roberts, and Ridley Scott, to name a few.

And two people who helped develop the motion picture industry were both southpaws: Charlie Chaplin and Thomas Edison.

Lefties are about 10% of the population and we often promote the theory that we’re more creative than righties, but it’s an exaggeration: there are a lot of talented right-handed folks.

Nobody knows the cause. It might be genetic or it might be something that happened during the birthing process. Whatever the reason, scientists have discovered that lefties’ brains are indeed shaped differently. Was this from birth or something else? Lefties are right-brain dominant, while the left brain is more dominant in right-handed people.

Jack Fincher is an icon among the 10%: He wrote the book “Lefties,” which explores the southpaw world. As a bonus, he was a Golden Globes nominee for his 2020 “Mank” script. He’s also the father of filmmaker David Fincher, who’s wildly talented even though he’s right-handed.

Jack Fincher’s book is witty and thoughtful and asks questions like: Which hand do you draw with, throw a ball with, catch with, swat flies with?

Many people do sports with one hand, but write with the other. For example, Nolan brushes his teeth with his right hand, but writes with the left — and the writing defines your handed-ness.

Fincher also points out the history of oppression. Some have considered left-handed people to be the mark of the devil; and the word “sinister” comes from the Latin word for “left.” And while we’re celebrating, let’s not forget that Billy the Kid, Jack the Ripper and the Boston Strangler were all left-handed.

But there are many lefties worth celebrating, also including Albert Brooks, James Cameron, Kurt Cobain, Morgan Freeman, Judy Garland, Bill Gates, Jimi Hendrix, Spike Lee, Marlee Matlin, Gavin Newsom, Ben Stiller, Queen Victoria and Prince William. In the U.S., we had a long run of southpaw presidents, 1980 through 2017: Ronald Reagan, George H.W. Bush, Bill Clinton and Barack Obama. The only exception in that timeframe was George W. Bush (2001-2009).

Why? Who knows?

The only thing that matters is that they’re worth celebrating. So let’s use our left hands to give them a pat on the back.
