The RUSHMORE star admits Coppola's direction in the film, in which he portrays late French royal KING LOUIS XVI, was unique at times.

He says, "I was insecure with Sofia in the beginning because she could see right through everything I did.

"But, because she's my cousin, she was like a library and she would reference a story from when we were five and that would help me in a scene.

"It was kind of unfair because nobody else had that with the director."
