 The pressbook for the film goes into detail about several of the  scenes, including one sequence that was cut from the film.  Apparently they filmed an entire sequence where young Christina runs  away from home and Joan goes out looking for her in her car. The  classic cars that were necessary for the film caused a big stir in  the neighborhood where the scene was filmed, and one of the people  stopped in traffic so as not to ruin the scene was  Barbra Streisand (qv), who apparently spent time hanging out with  Faye Dunaway (qv) between takes.
