Sarah Robertson (played by Zoe Saldaña ) is a senior risk analyst at the fictional investment firm. She works directly under Peter Sullivan (Zachary Quinto) and alongside Seth Bregman (Penn Badgley). Review of Sarah Robertson’s Role 1. The Moral Compass in the Room Unlike most of the senior executives who prioritize firm survival and personal bonuses, Sarah represents the ethical unease of a mid-level employee who still has a conscience. When she realizes the firm is dumping toxic assets on unsuspecting buyers, her disgust is visceral. She asks the obvious question everyone else avoids: “Is this legal?” — and later challenges the morality outright.

8/10 — essential, well-acted, but deserved a few more scenes.

Here’s a concise review of ’s role in the 2011 film Margin Call , as her character is often discussed in analyses of the film’s ensemble.

Sarah is positioned between the quantitative analysts who discover the problem (Sullivan, Eric Dale) and the cold-blooded decision-makers (Tuld, Sam Rogers, Will Emerson). She never becomes a key decision-maker, but her reactions — anger, fear, resignation — mirror what the audience likely feels. This makes her one of the most relatable characters in the film.
