In addition to Jennifer Ehle, Stephen Spinella also was naked in his Tony-winning role.
Tony nominees who did not win include Toni Collette in The Wild Party, Daniel Sunjata in Take Me Out, and Ben Daniels in Les Liaisons Dangereuses.
"What was the name of that cheese that I like?"
"you can't run away forever...but there's nothing wrong with getting a good head start"

Nathan wasn't even nominated for that one, but the only nudity he did was a flash of derriére, and the group skinny dip behind a scrim in very dim light at the very end. I don't call that nudity.
Marin Mazzie, Vanessa Redgrave, and the Take Me Out and Love, Valour boys (most memorably, Daniel Sunjata and Justin Kirk, but for quite different reasons)
In the New York production, Will Swenson did bare all at the end of the first act. However, he was standing at the rear of the stage and under very dim lighting. So, you really didn't get to see much (RATS!!!!).
