Leonardo DiCaprio as King Louis XIV in The Man in the Iron Mask (1998)

“Over 14,000 costume changes was done and at times DiCaprio felt insecure about the way he looked. Co-star Gabriel Bryne explains to David Letterman on Late Night, "The first day we had to get into costumes, he (DiCaprio) called me over onto the set and asked, ‘Gabriel, do I look like an idiot?’ I said, 'Leo, every woman in the entire universe is madly in love with you. Why would you look like an idiot?’ He then counters with, 'Well, I just looked at you and you look like an idiot!’”
