There’s a familiar face in the latest Marvel action movie, “Spider-Man: Homecoming.”

It’s Harvard Business School’s dean of seven years: Nitin Nohria.

In the movie, Peter Parker (a.k.a. Spider-Man), played by Tom Holland, is getting ready for his homecoming dance. He watches an instructional video on how to tie a tie and—lo and behold—it is Nitin Nohria who teaches the superhero to tie a Windsor knot. Nohria’s official title in the movie is “Dean Crimson.”

“Spider-Man: Homecoming” has grossed $459 million worldwide since its release and made $117 million just on the opening weekend. Though the movie has received high praise from viewers—garnering a 93% on Rotten Tomatoes—critics have given it mixed reviews ranging from “captivating” to “disheartening”.

“Spider-Man: Homecoming” came out on July 7 and is still playing in theaters around the greater Boston area. Nohria’s cameo is towards the end, and while his appearance may be short, what’s a superhero if they can’t untie their Windsor knot dramatically?
