‘A Mistake’ Review: Elizabeth Banks Gives a Tightly Wound Performance in Christine Jeffs’ Somber Medical Drama (2024)

New Zealander Christine Jeffs, who turned heads with her homegrown 2001 debut Rain before segueing to U.S. projects with Sylvia and Sunshine Cleaning, returns to features after a 16-year break with A Mistake. Sensitively observed, measured and perhaps somber to a fault, the medical drama about accountability is most notable for Elizabeth Banks’ compelling lead performance as a distinguished surgeon facing the professional and personal consequences of a questionable decision in the operating theater.

This is an intelligent, small-scale movie that never sensationalizes its material, adapted by Jeffs from the 2019 novel by Carl Shuker. It digs into thorny questions about human error and responsibility in an environment where people are looking to assign blame, as well as the bureaucratic evaluation process by which medical professionals are ranked according to results. While A Mistake feels too muted to cut it as a theatrical release, the film should find an audience on streaming services.

Elizabeth Taylor (Banks) is a surgeon in an Auckland hospital, considered among the best in her field. During a laparoscopic procedure on Lisa (Acacia O’Connor), a young woman with advanced septicemia, Liz entrusts her student doctor, Richard (Richard Crouchley), to insert the last trocar to drain fluid. He misjudges the amount of pressure required, rupturing an intestinal artery and necessitating a more invasive surgical fix.

Anyone squeamish about blood and internal organs might have a hard time watching the graphically detailed operation, with images from the laparoscopic camera magnified on video monitors.

The scene gives us a succinct take on Liz as both a doctor and a nurturing leader of her small team, including Richard and scrub nurse Robin (Mickey Sumner), who is also her romantic partner. Liz is calm, self-possessed and good-humored, clearly practiced at keeping stress to a minimum in the operating theater, so when Richard starts freaking out over his error, she quickly talks him down and gives precise instructions as they deal with the emergency. Only once she steps away from the table and removes her gloves and mask do we see the strain on her face.

Jeffs punctuates the action with Liz’s ferry crossings between work and her house across the harbor. The wake churned up by the boat seems to suggest turbulence ahead. Sure enough, bad news comes via text during her commute the next morning, informing her that Lisa died during the night in Intensive Care.

Richard is highly agitated, but Liz insists that the patient probably wasn’t going to make it anyway: “All we can do now is move on. Get past it. Get better. Learn.” But moving on becomes more challenging when Lisa’s grieving parents (Rena Owen, Matthew Sunderland) ask to see Liz, wanting detailed answers about why their 29-year-old daughter died.

With steadily building intensity, the film explores the ripple effect of Liz’s decision during the surgery. Her insistence on taking full responsibility and protecting Richard places her in the public firing line when Lisa’s parents file a formal complaint and take their story to the press. It also causes internal problems at the hospital, where the punctilious head of surgery, Andrew (Simon McBurney), is focused on protecting the institution’s reputation.

Banks gives a steely, largely internalized performance through the establishing scenes, gradually letting emotion creep in as Liz grows more isolated and even Robin pulls away to safeguard her job.

As the fallout from the patient’s death continues, Liz attends a surgical safety conference and is passionately outspoken about her objections to a new push for greater transparency from hospitals, with full results of surgeries to be made public. She argues that good doctors will start refusing to operate on the most vulnerable patients rather than risking their reputations and being hung out to dry by hospital administration: “People will be crucified.”

A tragedy hastens her unraveling even as it presents a damage-control opportunity to Andrew, played by McBurney as a chilly, mildly condescending man, more bureaucrat than medic at this stage in his career. “It’s called cleaning the wound, Elizabeth,” he tells her, while stressing that they need to agree on one version of what happened.

But Liz bristles at letting anyone else be scapegoated for her own error of judgment. In an affecting final scene, she visits Lisa’s parents to give them a full account of everything that happened, both under her watch and later, in the ICU.

Frank Ilfman’s score echoes the restraint in Jeffs’ script and direction, slowly swelling from its delicate beginnings into more melancholy territory and then escalating dramatically as the conflicts peak.

While the movie might be too unwaveringly downbeat in tone for some audiences, A Mistake functions as both an empathetic character study and a thoughtful examination of professional ethics, culpability and forgiveness, showing equal compassion for people on both sides of a devastating situation. It also serves as a welcome reminder of Banks’ sturdy dramatic skills.
