Its just a bad idea for a movie anyway. Shoes ain't the problem, Auntie Art! Without the theatre itself as its own framing device, any faithful film of GYPSY is bound to be a meandering, twee affair where you sit there going, "Jesus, who cares about these boring people?" and the numbers themselves are not enough of a payoff. I don't think anyone could make it work. THAT'S the reason Arthur should have pulled the plug From the article, it sounds to me like Sondheim was the only one involved who understood this, even if it was or wasn't subliminally.
"Impossible is just a big word thrown around by small men who find it easier to live in the world they've been given than to explore the power they have to change it. Impossible is not a fact. It's an opinion. Impossible is not a declaration. It's a dare. Impossible is potential. Impossible is temporary. Impossible is nothing.”
