The “Brain Games” will play out in New Orleans on Sunday’s episode of the NatGeo series.

In an episode titled “Brains Behaving Badly,” host Jason Silva visits The Big Easy to explore the brain and bad behavior as related to the Seven Deadly Sins.

“A series of games and experiments demonstrate how the brain has an evolutionary predilection toward doing the wrong thing,” a news release says. “Dr. Piers Steele from the University of Calgary shows how sloth affects the brain. Dr. Carrie Wieland from Tulane University puts the evolutionary origins of envy to the test ... and behavioral expert Dr. Alex Cohen of LSU shows us how the brain can switch to anger even when it should be perfectly happy.”

Also watch magician Jamy Ian Swiss trick a group of gamblers into being greedy, and Dr. Abigail Baird, associate professor of psychology at Vassar College, explore lust and what drives the brain wild.

“Brain Games: Brains Behaving Badly” airs at 8 p.m. (cable Channel 108).

Rachal tackles another ‘Broken Skull Challenge’

She took on the grueling “Skullbuster” course and won. Now, a Prairieville woman heads back to “Steve Austin’s Broken Skull Challenge” to defend her title.

Mother-of-four Emily Rachal, who won the $10,000 prize two weeks ago, will go up against the top contestant in Sunday’s episode of the CMT series hosted by retired pro wrestler Austin.

In the series, the contestants are pared down via three challenges designed to test their strength, stamina and endurance, with the one remaining competitor taking a shot at the “Skullbuster.” The daunting, timed course includes running, jumping, climbing and swimming.

The show airs at 7 p.m. (cable Channel 56).

Casting calls

Doron Ofir Casting is looking for America’s under-appreciated moms.

If the kids are rebellious, and the husband isn’t stepping up, you may be a fit for this new show “that will aim to help families appreciate Mom once and for all.”

Interested moms with three or more children, can email their stories to momcasting@brightroadprods.com. Include a brief bio, family photo, contact information and city/state you live in.

Also, the creators of the Oscar-nominated “Beasts of the Southern Wild” are reaching out to area nonactors to fill two “very specific roles” in their next film:

Female caucasian, age 30-40. A strong, hard-working mother with a twinkle in her eye and joy in her heart.

Male caucasian, age 50-70. Tall with angular facial features. A tough man whose hard life and rough exterior mask a trustworthy soul.

The casting call stresses that no acting experience is required. Anyone matching either description can send in a photo — a recent selfie, snapshot or family photo — and contact information to c13auditions@gmail.com. For further information, call (504) 408-1685.

The Louisiana-made “Beasts of the Southern Wild” features first-time area actors Quvenzhané Wallis, then a 9-year-old from Houma and, playing her dying father, Dwight Henry, in leading roles.
