From Chicago Sun Times:

Before shooting Lincoln, Spielberg took his star Daniel Day-Lewis through a tour of Gettysburg, where they got a bit of special consideration.

“I got to put on the white surgical gloves and hold the hat of Lincoln,” Spielberg marvels. “It was awe-inspiring. It was also intimidating. I had the urge to see if it fit and I didn’t dare.

“I would never dare. My hands actually began to shake just thinking about it.”

Day-Lewis adds with a laugh, “There should be a special jail for people who try on the hat.”

Spielberg and Day-Lewis discuss touching Lincoln’s famous headwear.
