The uncertainty can be really daunting if you place too much emphasis on results in life and too much emphasis on the finality in life rather than focusing on the process. As an artist I think you really have to be involved in the process if you put too much emphasis on the finality, of course it's a let down. You're gonna be upset. But, the truth is you can't control it. You can't control it.
Every actress has options, and wisely so.
Think about it this way. It could happen. She'd have to quickly run back upstairs and put on the alternate dress. When they make movies and Sharon Stone is filming Basic Instinct , they have three or four copies of the same outfit so that doesn't happen. Alternates are important.
