The movie did great things for the stage show. It brought CHICAGO to a much wider audience who might not have given the show a second glance had it not been for the movie. (did that make sense? Im sick and heavily medicated lol)
You also have to remember that the Ambassador is a sigificantly smaller house than the Shubert, so it's easier for Chicago to fill it to capacity. The Weisslers' may not be the most favored producers on Broadway, but they certainly seem to know what they're doing if Chicago has stayed open this long... and good for them -- it's kept a few of my friends very gainfully employed and if for nothing else, I'm thankful for that.... as are many other people.
