My Professor's Guide to Murder Cast: A Plain Breakdown

The Netflix movie My Professor's Guide to Murder came out in August 2024 and it's a light romantic-comedy-mystery set at a university. It's not trying to win awards. It's a two-hour watch you can put on when you want something harmless. The My Professor's Guide to Murder Cast is mostly made up of actors known for TV roles rather than big film careers, which explains why some faces feel familiar but you can't immediately place them. Erin Moriarty plays Callie, the transfer student who moves into her roommate's dorm and quickly gets tangled in a murder investigation. Moriarty is probably the most recognizable name on the poster. She comes from The Boys, where she plays Starlight, so if you've watched that series you already know her face. Her performance here is competent but not particularly challenging material. Jordana Lagracia plays Kaela, Callie's roommate and central friend figure. Lagracia has a background in television and theater but isn't a household name. Her role is mostly reactive, serving as the grounded counterpoint to Callie's impulsive behavior.

Logan Miller takes on the lead love interest role as a graduate teaching assistant named Ben. Miller has been in teen comedies and rom-coms for most of his career, so this fits a well-worn lane for him. He does the job without drawing attention to himself, which is exactly what the script calls for. David Corenswet appears in a supporting role as a professor named Dr. Harlan. Corenswet was relatively unknown at the time of filming and had only small TV and indie film credits. Things changed pretty dramatically after that. He went on to play Superman in the DC Universe, so his presence here is worth noting for anyone tracking career trajectories. His screen time is limited but he carries the authority figure typecasting naturally. Amy Landecker plays Dean Margaux, the no-nonsense department head. Landecker is a character actress with decades of credits under her belt. You've likely seen her in Brooklyn Nine-Nine or Transparent. She's the kind of performer who elevates every scene she's in, even when the writing doesn't deserve it.

Tom Wright appears as a local detective investigating the murder. He's a British actor with a long list of TV and film credits. His role follows the standard procedural detective template, and he fills it adequately. The rest of the cast consists of ensemble students and faculty members who exist to provide suspects and red herrings. None of them have leading status. Most are working actors cycling through guest spots and small roles. One thing people often miss when looking at this cast is the director. Jonathan Wright directed the film, and his background is primarily in short films and television episodes rather than features. That shows in the pacing. The movie runs long in the second act and the murder mystery mechanics feel undercooked compared to the romantic comedy beats.

I actually tried to track down audition stories or behind-the-scenes material about how this cast was assembled, but there's very little publicly available. The production kept a low profile, which is typical for Netflix mid-budget romantic comedies. They cast for familiarity and affordability rather than star power. That's the business reality of a project like this. There's also a smaller cast of campus security, local police officers, and fellow students sprinkled throughout. Look for Michael Cramer and Samantha Soucie in minor supporting roles. These are credit-building appearances for working actors who will likely move on to other projects within a year or two. What I found interesting watching this is how the ensemble chemistry ranges from natural to stiff depending on who's on screen. Moriarty and Miller have decent rapport, which matters because the entire romantic subplot depends on that connection holding. Landecker and Corenswet share a few scenes together and they work well as a bureaucratic duo. The student ensemble feels less integrated, which the script mostly ignores by giving those characters thin functionality.

If you're searching for this cast because you recognize someone and want to know their name, start with Erin Moriarty and work outward. After that, David Corenswet is the next most likely person to trigger recognition. The rest of the ensemble will require a quick IMDb scroll for most viewers.
