Jonathan Groff attends a For Your Consideration event for his Netflix series Mindhunter on Friday night (June 1) at Raleigh Studios in Los Angeles.

The 33-year-old actor was joined at the event by co-stars Anna Torv, Holt McCallany, and Cameron Britton, as well as director David Fincher.

David opened up about how he had his cast do many, many takes of each scene.

“The scene with Happy [Anderson] was 11 pages. We had three cameras outside the cage, and we’d do a nine-and-a-half-minute take,” David said (via IndieWire). “We didn’t have a break, well we broke for lunch — I would say we did it 75 times in the day.”

“David was really specific with us about every single word, and every single turn of the scene; he was critically specific about the purpose,” Jonathan said. “On the days of shooting, we would go in the room, sit down, and talk about how leaning forward could change the dynamic of a conversation.”
