‘Equity’ is a tense women-of-Wall-Street drama

A mature look at the unwritten rules for women in banking.

Wall Street films have traditionally been raucous affairs, featuring bankers, investors, fund managers, and traders as hedonistic party boys. If a woman showed up, she’d be there to take shorthand or to strip. Sometimes both.

It’s all the more reason to celebrate director Meera Menon’s second feature, “Equity,” an intensely intelligent, well-written, and mature exploration of the unwritten rules women have to follow if they want to succeed in high finance.

Billed as “the first femaledriven Wall Street movie,” “Equity” is the brainchild of two actor-producers: Sarah Megan Thomas and Alysia Reiner (“Orange Is the New Black”), who cowrote the original story after conducting extensive interviews with women who work in the financial industry.

From interviews? On paper, the film sounds like it’s bound to be a dry, droning documentary, a quasifeminist tract with a long list of grievances about the industry’s inherent sexism.

“Equity” is anything but dry.

It’s an exciting, smartly sexy, suspenseful little crime drama that evokes classic Hollywood film noir.

A subtle piece of drama that feels like a quieter, lessmadcap version of “Mad Men,” “Equity” attempts to capture the female Wall Street experience through sustained portraits of three women. Strong and capable, each has to make serious sacrifices to get ahead in the world. One sacrifices the opportunity to have a family; another, her moral scruples; the third, any chance of an inner life.

“Breaking Bad’s” Anna Gunn is superb as Naomi Bishop, an experienced investment banker in her 40s who specializes in reeling in tech firms to hire her bank as the underwriter for their IPOs.

It takes a little work to warm up to Naomi, who seems so guarded, aloof, and imperious as to be unapproachable.

Thomas stars as Naomi’s younger protegee, Erin Manning, who does most of the older woman’s grunt work.

Equity sometimes feels like a social-dynamics textbook, but the characters are well-drawn and compelling.

The action hinges on Naomi’s bid to land a social media company run by a snot-nosed, sexist young turk. The process will lead each woman to the brink of corruption.

We need more films like this — serious but not maudlin dramas about the way we live now and the toll it takes on our souls.
