I've always imagined Amy Adams as Janet, finding a triple threat who is a name is going to be very hard. Adams and Anna Kendrick are the first two people that come to mind that somewhat come close to being triple threats, but not really. There are no more Rita Morenos, Gene Kellys, and Liza Minnellis. "Show Off" on film would be great.
Love the idea of Nicole Kidman as the Chaperone, someone really unexpected, who'll be having a great time with an old friend (Rush). Really, the roles are great for this, I certainly hope it happens.
