Please make sure, when you buy a ticket for “Precious: Based on the Novel ‘Push’ by Sapphire,” to pronounce the title in full. I know you will. There was a plan to call it “Push,” until another movie got there first. But why not call the new one “Precious,” and leave it at that? After all, Deborah Kerr didn’t star in “The Innocents: Based on the Novella ‘The Turn of the Screw’ by Henry James,” and Dustin Hoffman didn’t star in “Rain Man: Based on the Overwhelming Desire to Win an Academy Award by Dustin Hoffman,” so why the change in rubric?
