Durante el rodaje de Día de la marmota (Groundhog Day), los asistentes de producción, cansados de la dificultad para ubicar a Bill Murray, le pidieron que contratara un asistente. Murray reclutó a un sordo que hablaba solo en lenguaje de señas, que ni él ni nadie en el equipo de producción comprendía.
Jeff Labrecque. "'Groundhog Day': My favorite Bill Murray story". Entertainment Weekly, 2 de febrero de 2012 https://ew.com/article/2012/02/02/groundhog-day-bill-murray/ “Bill had all these obvious resentments toward the production, so it was very hard for a time to communicate with him. Calls would go unreturned. Production assistants couldn’t find him. So someone said, ‘Bill, you know, things would be easier if you had a personal assistant. Then we wouldn’t have to bother you with all this stuff.’ And he said, ‘Okay.’ So he hired a personal assistant who was profoundly deaf, did not have oral speech, spoke only American sign language, which Bill did not speak, nor did anyone else in the production. But Bill said, ‘Don’t worry, I’m going to learn sign language.’ And I think it was so inconvenient that in a couple weeks, he gave that up. That’s anti-communication, you know? Let’s not talk.”
