When lifelong Yankees fan Jack Nicholson refused to wear a Red Sox hat during the shooting of an Oscar-winning classic

Lifelong New York Yankees fan Jack Nicholson refused to wear a Boston Red Sox hat while shooting the Oscar-winning classic "The Departed," which hit theaters in 2006.

The Martin Scorsese-directed thriller bagged four Oscars. The 50-year-old actor Mark Walhberg, who was nominated for best supporting actor for his role as Sgt. Dignam, also shared a scene with Nicholson. Nicholson played the role of Frank Costello, the mob leader.

Nicholson was very straightforward about not wanting to wear a Boston Red Sox hat. He also spoke about how his co-star Kristen Dalton, who played the role of his beloved in the movie, sported a Red Sox hat in the film. He said that she did so to hint at a domestic disparity. Dalton also made sure that the Boston fans would be enraged by the fact that the die-hard Yankees fan, Nicholson, refused to wear a Red Sox hat.

Speaking to New York Magazine, Nicholson said:

"First of all, they wanted me to wear a Red Sox hat, but I said, all things being equal, I don’t want to."
